Cortical stacks do work as a way to revert pawns back to humanity from my testing so far, so I have a way to revert this ghoul back as a small goal along with the monolith.

tested it and it won't let you use normal resurrection mech serum, instead you gotta use the special ghoul resurrection serum to actually revive ghouls, if the head is missing however then the ghoul can't be revived.
