Ehh, I don't think it'd do that well online, but I'd say go for it, just for the heck of it, as long as it doesn't get in the way of producing the normal ones.
As for the MMO version, ehh again. That would be tough. I picture it in my mind, and all I see is people with swords and shields I think that'd be too weird. They got the races, and a bit of weapons, but they'd have to make the world a LOT bigger.
