Sumo Wresting Game Type Idea

So, I was laying in my bed having trouble falling asleep. So I said to myself "I might as well come up with an idea for a custom game. This is when an idea hit me. What if there was a game mode that took place in the same place as the blitzcrank volleyball where each team has to knock a designated player on the other team out of the designated area. I guess I have new game mode to design.
