The Avengers as a Western
Steve is the Sheriff. Clint is his deputy. Tony is the Blacksmith. Natasha runs the Saloon. Bruce is the physician with a split personality and Thor gets into a hell of a lot of tavern brawls.
Together, however, they manage to bring order to the once corrupt town of Triskelion.
Remember The Avengers as a 70s Cop Drama? A Western might be cooler.
