Paintball game mode?

I just had this idea. What if there was a paintball game mode? A paintball gun would be mounted on the front of the kart and the normal battle arenas could be used. The players would try to hit each other with paintballs and there would be a time/hit limit (5 minutes or 30 hits? changable?). Each kart would have a different, random paintball color. If the paintball hit the front/side of the kart, it would make a splotch on the kart and a smear on the screen (right side, front or left side, depending where it hit. that would slowly drip off. If it hit the back, it would just make a splotch This would be somewhat tactical, you want to hit your opponent on the front/side to smear their vision so they have trouble seeing/hitting you. I think this would be a fun addition to the game.
