I'm organizing a trip for me, my SO, and a bunch of our queer friends for the end of August and man I think we would love something like this. (I don't know enough about locations to recommend anything personally, though.)
This idea seems really great imo. I'm very interested in subscribing if a mailing list like this crops up.Here is Boston there was a Guerrilla Queer bar that was popular for a while, where it would be announced on social media that Bar X would be the gay bar on a particular night, word would spread through a mailing list and social media and we would take over a particular bar on a particular night. That might be a more fun way of doing things.
