I hate to say it, but I don't think this is gonna work. We had enough trouble starting a regular Grail War RP where it required 14 people. Something like this... I don't know if it's even possible to run, even with a godly GM. CE is able to work with that many because it's more freeform, and people are more free to kinda just wander off and do their own thing. This though... this would be chaos.
I appreciate you trying to help out anyway, it's just this isn't all that feasible.
