I feel like having characters be out for the entire game would be less interesting for that player once they're out, so they'll just have to go back to their side

Aye. I used to be in the Society for Creative Anachronism, and they did it a similar way during "big" field battles. Fighters who get hit place their weapons above their heads and walk off-field to a "resurrect point" of some sort, rehydrate, and go back onto the field at their side before starting fighting again.
