Having a system like this has been discussed a few times already btw. (Sorry no sources). And I think most people agreed that it would be a good addition.
Do note that the CBM is actually intended to be a one use automated surgery kit that does most of the hard work of the surgery.
“CBMs are surgery kits that contain all the tools required to install a cybernetic implant, also called bionics, in a human. They are automated in some ways, but manufacturers’ warranties insist on having a fully qualified technician and medical doctor to assist in the installation–in a proper medical facility.”
Yes, this does mean that crafting CBMs and getting them from corpses makes no sense at all.
