Any chance of having a similar Skittermander (Freerpg day) character pack like We Be Goblins did? At least the main characters. All the times I've ran WbG (pick a number) @ ReaperCon, having the prepainted minis of the main characters really has helped immerse the players into the game.
It doesn't have to be random packs like WBG was but say a Fast Force mini pack like Wizkids does for Heroclix.
