I would like if shipside medical was replaced with more advanced medicines like cyro revivals.
It gives command options to revive perma dead marines via advanced technology.
You could replace cyromarines with it.. in principle its the same; some marines get back in the game. But now you give marines an incentive to retrieve bodies, and give shipside something to do.
Make it multipart so its interesting. Like a brain surgery, followed by transfusion, followed by 3minutes in the cyro with the "unlocked" chemical. Then a body is revivable again.
And the marine can be hanging out in deadchat the whole time instead of bored in paincrit.. or bored on the dropship.
