Excellent list, SiBurning! I've enjoyed these topics whenever they came up here and it's good to have a "western central" thread for co-ordination.

One direct-to-video film you should add is 2004's GHOST ROCK, aka "The Reckoning." It's a potpourri western-- vengeful gunfighter, kung-fu, a ghostly girl gunfighter and 70+yeY-«old Adrienne Barbeau decking a guy with one punch. But it fits.
