a friend who makes missions uses an "almost dead" respawn which replaces your body with a sheet covered one until someone comes and revives you,
you as a player repawn on a different location until revived and then you are transported to your real body, so to speak.
perhaps something like that could be donw only have a static"body" that you can carry instead of a rocket launcher and you can take him to a medic or something who can revive him?
