[ELI5] Why aren’t brain transplants possible?

Question

If there is a brain dead patient and a person with multiple failing organs, why is it not possible to transfer the brain to from patient to patient? I understand there are many ethical reasons to give somebody another’s body, but if both had given consent then would it be possible and if not why?

Answer 1

To piggyback on the other comment, if you had technology sufficient enough to properly contact all of those neural pathways, then you have technology sufficient enough to just reverse brain death.
