Basically in table game do a roll base on charm stats is usually the case. I think the design and dialog is for 2 player, for that is already an amazing task to allow 2 player do decisions together and messing around. With more players, maybe a mod can do a poll cast for a vote decision, and if someone insist doing certain things, you can always make computer roll the dices. So yeah, mod would be totally doable, I just hope their engine is stable enough to let multiple connection into the game.
