This concept is definitely the way to go in my opinion. But I think it would be difficult to do unless four mats could be put down. It would be difficult to keep the rounds even. If you split into two pools of five, then four teams from each pool would be wrestling at each time. That means four total duals going on in round one. With only three mats, one of the round 1 duals would have to wait. It would be hard to continue to round two without having completed all the round one duals yet.

Perhaps there would be a way to work it out, but that is one problem I foresee.
