There's a few other adventures on itch, though I haven't tried them out A few small settings are here. You can search for the tags thirsty-sword-lesbians or powered-by-lesbians there
Age of Ravens also did a Star Wars setting called Thirsty Force Nightsisters, which you can watch a playthrough of here and here
The Cypher system people did put out a weird west book, sounds like a decent fit. Though honestly I think most any generic system would work pretty ok.
