I believe there were some dwarves (only a few) in the Battle of the last alliance and "on either side" as Tolkien mentioned in the appendix somewhere which meant some dwarves fought for Sauron. As far as I can tell, the notion of wicked dwarves is well-supported, thus a dark dwarves faction would be both lore-accurate and game-balancing.
