It's good to see more interest in longer time controls. You should confer with Tournaments (yes, that's his username) who is already running a similar thing. We're playing the second tournament now with 90+30 time controls. Note that if you want to use the current FIDE time controls you'll have trouble because there's no method of adding additional time after to the 40th move (a lot of programs seem to have that drawback, not just websites).
