Another take but an interesting thought, what if they did do the process on her and thus give her a new lease on life but due to her original body being an Omega Sentinel, it either self-repaired or was recovered and repaired and without her mind in it, the Omega Sentinel programming took over 100%, developing into its own AI in charge of her old body?
Something could be done to help her with Forge/Box/Trinary tech expertise.
Her story is extra tragic considering we've seen how she clearly cherished her humanity in Adjectiveless X-Men.
...and I wonder if he's inspired at all by the Netflix show "Sense8"? A group of a different strain of humans, all with something close to 'telepathic' powers (yeah, more complex but close), who have very interesting sexual relationships due to the expansion of their consciousness and awareness. Portrayed as wonderful and beautiful to the participants (albeit with an adjustment period) but a bit odd to 'normals' or 'offputting' to people who really don't like relationships other than the traditional kind.
Did you actually watch "Sense8" because it was a hell of a lot more than that, had some very innovative narrative structures, detailed plotting, and explored multiple themes and concepts. The ability for people to experience the physical expressions of love of multiple people, including their own, at once was an extension of the growth of increased understanding and empathy that was the main theme of the series.
ETA: I could see Hickman doing something similar with the telepaths involved. If Jean connects all 3 (or four) of them to where individually and collectively they experience the love, lust, play, etc. of everyone, even the areas of uncomfortability and the corrections to mitigate that... it could be a very interesting exploration of these themes.

We are not sure that The Five's procedure can work with humans. Perhaps the eggs produced by Goldballs are only compatible with mutant DNA.
