I'm not sure if it's possible but maybe make simple 'ghetto' surgery possible to do on yourself while sitting in a chair? I can see an Antagonist sitting in some corner of maintenance stitching themselves back together in a haphazard manner, obviously with the associated risks. Most of the items for this can be obtained relatively easily as well, as they are just things like wire, duct tape, wirecutters ect. I guess a cure all drug would be easier - for a TC cost, but this just seems like something cool to layer on top of that.
