Could be pretty cool. I like what I see of the setting and I have a lot of respect for Mark Latham having really enjoyed his Warhammer Historical Legends of the Old West.
That said, I'm already in deep on two minis lines (+ heroscape) with a bunch of stuff to paint. Not sure I need to get in on a third. If I were to it would likely be Dungeon Saga...
...however, this dude in a Blue Demon mask on the megaton-games website is a sweet mini...
