The only thing I'd be concerned about is if this does take off you could potentially attract less than savory players who's goal is to only win. It sounds like when you did the original test these were all "known" players who wouldn't cheat.
Now introduce some players who may have played maybe 3 or 4 times and the attitude they bring might be more "play to win" rather than "vets" who might play to see how well they do but don't get caught up in the whole winning aspect.
Interesting nonetheless though and its good to see a positive after action report on testing a new gameplay style/type especially one that people say won't work out.
Also, from what I've been told, when there's bigger prize purses or such at stake cheating goes up exponentially. (eg. Winner of the tournament gets a $1000 prize purse or winner gets team sponsorship). It seems like this is a problem in Asia especially with speedball type airsoft games where everyone just shoots strings of plastic going at 700 FPS and lots of people ignore hits (I've seen a few videos on youtube of speedball type games and the pretty blatant cheating).
