We had this, it was called Medicball in western PA. Two medics per team wore pinneys and would rescue hit players by bringing them back to their side using the roller boards. If one medic got hit, the other medic could save him/her. If both medics got hit, you're f'd.

Also: Pin Dodgeball (sometimes called Pinball). Hit the pin on the other side of the gym (usually under the hoop) and everyone out on your team comes back in. Or catch dodgeball, where a catch brings everyone back in.

It takes you 5 minutes to put on a loose over-vest? I'm not saying change uniform. I'm thinking of those light mesh over-shirts you used to use in gym class to define one team (something like this) that would take maybe 10-15 seconds to throw on and could usually be done on the sidelines (or you can wear around your waist like players who keep towels).

Right now the rules say to switch you have to go report your eligibility status to the referee before every play and then the ref has to announce it to the defense before every play. If you want to go back to your original eligibility status, you have to go out of the game or wait for a clock stoppage/timeout.

That's silly and requires the refs to keep things straight which they've shown they can't be relied on to do this. (Just think of how many times the penalty is announced as one # when it was totally someone else; now imagine that being done on an eligible/ineligible play where the defense was told to block the wrong player by the ref announcing the wrong #).
