I’m not quite certain on the difference between Realms of existence that you speak about, or of mind states where the Khandas are progressively abandoned. But if using the Jhanas as basis, you might find some of the following useful.
SN36.11
"When I said this I was referring to the impermanence of conditions, to the fact that conditions are liable to end, vanish, fade away, cease, and perish.
But I have also explained the progressive cessation of conditions. For someone who has attained the first absorption, speech has ceased. For someone who has attained the second absorption, the placing of the mind and keeping it connected have ceased. For someone who has attained the third absorption, rapture has ceased. For someone who has attained the fourth absorption, breathing has ceased. For someone who has attained the dimension of infinite space, the perception of form has ceased. For someone who has attained the dimension of infinite consciousness, the perception of the dimension of infinite space has ceased. For someone who has attained the dimension of nothingness, the perception of the dimension of infinite consciousness has ceased. For someone who has attained the dimension of neither perception nor non-perception, the perception of the dimension of nothingness has ceased. For someone who has attained the cessation of perception and feeling, perception and feeling have ceased. For a mendicant who has ended the defilements, greed, hate, and delusion have ceased.
And I have also explained the progressive stilling of conditions. For someone who has attained the first absorption, speech has stilled. For someone who has attained the second absorption, the placing of the mind and keeping it connected have stilled. … For someone who has attained the cessation of perception and feeling, perception and feeling have stilled. For a mendicant who has ended the defilements, greed, hate, and delusion have stilled.
There are these six levels of tranquility. For someone who has attained the first absorption, speech has been tranquilized. For someone who has attained the second absorption, the placing of the mind and keeping it connected have been tranquilized. For someone who has attained the third absorption, rapture has been tranquilized. For someone who has attained the fourth absorption, breathing has been tranquilized. For someone who has attained the cessation of perception and feeling, perception and feeling have been tranquilized. For a mendicant who has ended the defilements, greed, hate, and delusion have been tranquilized.”

Also, there is the passage in MN111, which clearly illustrates the absence of the aggregates, while in the 8th Jhana. In all the previous stages there was still perception up until that state, when even perception has ceased

Furthermore, going totally beyond the dimension of infinite consciousness, aware that ‘there is nothing at all’, he entered and remained in the dimension of nothingness.
And he distinguished the phenomena in the dimension of nothingness one by one: the perception of the dimension of nothingness and unification of mind; contact, feeling, perception, intention, mind, enthusiasm, decision, energy, mindfulness, equanimity, and attention. He knew those phenomena as they arose, as they remained, and as they went away. He understood: ‘So it seems that these phenomena, not having been, come to be; and having come to be, they flit away.’ And he meditated without attraction or repulsion for those phenomena; independent, untied, liberated, detached, his mind free of limits. He understood: ‘There is an escape beyond.’ And by repeated practice he knew for sure that there is.
Furthermore, going totally beyond the dimension of nothingness, he entered and remained in the dimension of neither perception nor non-perception.
And he emerged from that attainment with mindfulness. Then he contemplated the phenomena in that attainment that had passed, ceased, and perished: ‘So it seems that these phenomena, not having been, come to be; and having come to be, they flit away.’ And he meditated without attraction or repulsion for those phenomena; independent, untied, liberated, detached, his mind free of limits. He understood: ‘There is an escape beyond.’ And by repeated practice he knew for sure that there is.
Furthermore, going totally beyond the dimension of neither perception nor non-perception, he entered and remained in the cessation of perception and feeling. And, having seen with wisdom, his defilements came to an end.

"Furthermore, a noble disciple reflects: ‘Sensual pleasures in this life and in lives to come, sensual perceptions in this life and in lives to come, visions in this life and in lives to come, perceptions of visions in this life and in lives to come, perceptions of the imperturbable, and perceptions of the dimension of nothingness; all are perceptions. Where they cease without anything left over, that is peaceful, that is sublime, namely the dimension of neither perception nor non-perception.’ Practicing in this way and meditating on it often their mind becomes confident in this dimension. Being confident, they either attain the dimension of neither perception nor non-perception now, or are freed by wisdom. When their body breaks up, after death, it’s possible that the consciousness headed that way will be reborn in the dimension of neither perception nor non-perception. This is said to be the way of practice suitable for attaining the dimension of neither perception nor non-perception.”
When he said this, Venerable Ānanda said to the Buddha: “Sir, take a mendicant who practices like this: ‘It might not be, and it might not be mine. It will not be, and it will not be mine. I am giving up what exists, what has come to be.’ In this way they gain equanimity. Would that mendicant become extinguished or not?”
“One such mendicant might become extinguished, Ānanda, while another might not.”
“What is the cause, sir, what is the reason for this?”
“Ānanda, take a mendicant who practices like this: ‘It might not be, and it might not be mine. It will not be, and it will not be mine. I am giving up what exists, what has come to be.’ In this way they gain equanimity. They approve, welcome, and keep clinging to that equanimity. Their consciousness relies on that and grasps it. A mendicant with grasping does not become extinguished.”
“But sir, what is that mendicant grasping?”
“The dimension of neither perception nor non-perception.”
“Sir, it seems that mendicant is grasping the best thing to grasp!”
“Indeed, Ānanda. For the best thing to grasp is the dimension of neither perception nor non-perception.
Take a mendicant who practices like this: ‘It might not be, and it might not be mine. It will not be, and it will not be mine. I am giving up what exists, what has come to be.’ In this way they gain equanimity. They don’t approve, welcome, or keep clinging to that equanimity. So their consciousness doesn’t rely on that and grasp it. A mendicant free of grasping becomes extinguished.”
“It’s incredible, sir, it’s amazing! The Buddha has explained to us how to cross over the flood by relying on one support or the other. But sir, what is noble liberation?”
“Ananda, it’s when a mendicant reflects like this: ‘Sensual pleasures in this life and in lives to come, sensual perceptions in this life and in lives to come, visions in this life and in lives to come, perceptions of visions in this life and in lives to come, perceptions of the imperturbable, perceptions of the dimension of nothingness, perceptions of the dimension of neither perception nor non-perception; that is identity as far as identity extends. This is the deathless, namely the liberation of the mind through not grasping.
So, Ānanda, I have taught the ways of practice suitable for attaining the imperturbable, the dimension of nothingness, and the dimension of neither perception nor non-perception. I have taught how to cross the flood by relying on one support or the other, and I have taught noble liberation.
Out of compassion, I’ve done what a teacher should do who wants what’s best for their disciples. Here are these roots of trees, and here are these empty huts. Practice absorption, Ānanda! Don’t be negligent! Don’t regret it later! This is my instruction to you.”
That is what the Buddha said. Satisfied, Venerable Ānanda was happy with what the Buddha said."

This was said by the Lord…
“Bhikkhus, there are these three elements of escape. What three? The escape from sensual desires, that is, renunciation; the escape from form, that is, the formless; and the escape from whatever has come to be, from whatever is conditioned and dependently arisen, that is, cessation. These, bhikkhus, are the three elements of escape.”
Having known the escape from sensual desires
And the overcoming of forms,
One whose energy is always ardent
Reaches the stilling of all formations.
Such a bhikkhu who sees rightly
Is thereby well released.
Accomplished in knowledge, at peace,
That sage has overcome all bonds.
