Typically you probably wouldn't have an entire clan roundrobbining one thread unless you set up game events to be best played that way. 4-5 is a good number to start with and see how it works out.
It really depends on the players you get. Acceptability of hand waving is something that's more defined by the player base than anything the mod or the game does.
Anyway from what it sounds like you want to do with this game a set up like this might be the best way to keep things organized and people on task instead of spread out all over. Someone else might have a better idea though. Good luck with your game!
eta: not sure where you would find anyone to help mod though unfortunately sorry
