This just popped into my mind.

Team LRS

Both players on each time have a level-specific amount of lives. Once they lose their lives, they are unable to fight anymore. However, the scoring depends on how many players are on the victorious team, as in if there was one player left in the winning team, the whole team would get one point. If there were two players, the team would receive two points. Also, XLRS scoring could be implemented so that each time someone loses a life the opposite team gets a point, and if someone loses all his lifes, the opponents receive three (or also level specific) points.
