I've recently become aware that, once a character dies, any cyberware on their person simply becomes an item on their person, which can be taken just as easily as any other. With your bare hands. As in, you rip out the carefully installed, delicate chrome in meaty chunks with your bare fists. Which seems a little silly.
I propose that, to loot cyberware from a corpse, you need to enlist the help of a medical character. A ripper doc! Taking chrome from a dead body would probably be far easier than installing it, in regards to skill checks, but it seems like something an untrained guy wouldn't be able to do with much success. To make it so taking chrome is still viable, maybe make it so that chrome in a corpse won't decay until the corpse itself decays fully? Not sure about that, but there's my first idea about it.
