Old Cowboy TV Shows... in an Alternate Universe

Notes:

I tried the Bing AI out of curiosity. I decided to give old cowboy tv shows some love, as I really like those (as did my grandparents). Also, because I'm terrible at drawing realistic human faces.
Anyways, I tried to create a crossover between my favorite shows with the prompt: "Gunsmoke, The Rifleman, Rawhide, Bonanza, crossover". It failed to do so. Instead, it generated non-existent westerns with non-existent people, hence it was like an alternate universe.
