This sound like riskier healing with upside of hiding a corpse. I like it.
T health station as of right now: Spend x amount of points, spend a credit, deploy in "safeish area" (noone nearby/t room) get healed by what looks like a health station and noone can kill you a traitorous action if they didnt see you deploy it.
cannibalism perk: Spend a credit, kill someone/find a corpse in your area, "consume" a body destroying the dna and get healed by what looks like a traitorous action to any onlooker.
The point perk still has its upside of being able to trick innocents that you are healing legitly while the cannibalism perk has the upside of destroying evidence by what certainly looks like a t act to onlookers. I think this is risky enough healing to include in the game while ensuring counterplay; not a lot of free corpses end up in entirely safe areas to consume.
