The X-Men currently have a method to bring people back from death that can do precisely that.
Cerebro can create mental snapshots of mutant brain.
Five specific mutants, called The Five, then do the following:
Goldenballs/Egg creates a non viable egg as a foundation.
Proteus warps reality to make the egg viable.
Elixir catalyses the process of life and begins new cellular activity.
Tempus accelerates time so the egg develops to a desired age.
Hope synchronises The Five and lets them work at their best.
Then a telepath, Xavier, Jean Grey, Hope, whoever implants the mental snapshot into the now hatched egg and restores a deceased mutant to life.
They've used these resurrection protocols thousands, if not millions, of times in the current Krakoa arcs effectively beating death.
It's been mentioned edits can be made to the egg during development as requested and it's also been mentioned several requests have been made to put some minds into a body based off Magneto. Which is very much possible as Proteus inhabits bodies that are clones of Xavier as the way Proteus' powers work means he burns through his body the more he uses his powers so they have backups ready for him to use. When he has a lot of resurrections to do he may burn through a body in as short as a day it's that frequent.
The only limits in place are proof of death is required before someone can be resurrected to prevent two copies walking around. There is nothing stopping mind's being reborn in other bodies so the concept of a trans mutant is just as flawed as a trans character in Dungeons and Dragons where multiple options exist that literally can change a physical body from one sex to the other.
