Hmm, a very impressive outline for what could be a pretty schlocky idea if done poorly. I commend you. Definitely calls to mind several things; Abraham Lincoln: Vampire Hunter, Vampire: The Masquerade, 30 Days of Night, Mike Mignola's Baltimore and the Fright Night remake, maybe? Hopefully a bit of Red Dead Redemption, Deadwood and/or Hell on Wheels, too.

I'm definitely interested. \m/
