Organizing a tournament is very hard at this period, look at the Serioussam.su tournament. 1vs1 and single-elimination (anything other than single-elimination is a bad idea ) is pretty much the only way it could in any way work. I wouldn't have the time to play now either.
Easier would be to organize some teamgames, CTF and TDM modes in Rev could be cool, and more possible, since those would be a single event, not an ongoing project with walkover possibilities.
Who knows, maybe a working tournament could work at summertime, but the organization needs to be top notch.
