Team games are quickish like a 2p game, so doing a tournament is definitely possible especially for d12 during peak hours of live play. I would expect that you might need to allow for 4 hours plus for yourself as the organizer, and if you are also going to be playing in the games, maybe share the duties in organizing the tourney with someone. players can get impatient, and disappear, then you have to find subs, etc.. you will be multitasking with reading and sending messages and stuff, and it can be quite draining if you aren't use to it. As psymon says, it would be ideal to pre-organize it, especially your first live tournaments, and as you do more, with regular participants, they will understand the drill and they will run smoother.
