I really love the idea of them maintaining their bodies like the weapons they are. Definitely not a mainstream idea, but I really like it. That may end up factoring in some future fics.

Whether they end up in the medical wing voluntarily or otherwise, I see them using the buddy system. Ya know, just to be on the safe side, they attend each other's physicals, blood tests, emergency surgeries… Wouldn't want an unscrupulous (i.e., Hydra) doctor sabotaging SHIELD's greatest assets.
