My Suggestions

It would be possible to make more than one team. Depending on the amount of people you could make three teams or even more. The difference between each sides amount of participating players is the most troublesome part. Since we have many more people on the light side, it would be wise to have some of the dark players fight in two parties (still they get only the ToH points for winning once). Maybe make P/HPs leaders and let others join via rolling the dice?
I think it would be easily possible to get this kind of thing done if you think it through and??the idea itself is great.
