I think you should try a tourney like the way they do a type at Pevs Paintball Park. They call it streetball. It is a 3 man tourney and people sign up as individuals, no teams. Then, on the day of the tourney, a staff member/ tourney director will then pick 3 names out of a hat. Those 3 names are 1 team. You can have a schedule already out and then fill it in on game day by Team 1, Team 2..etc. If there is not enough people fill a team, then they should be able to have a free pass with walk-ons. It is a first come , first serve basis. There is np division (but only d5-d2 players, no d1 or semi-pro or pro) because it can end up anyway. It is a suggestion you should think about and you could always tweak the rules. Hope to play in a tournament this year !
