Well, the Bechdel test is intended to be a very low bar to pass, that doesn't indicate that a work is necessarily feminist in nature, but that it's not contributing to a specific non-feminist media representation.
The test being that there be two women, who speak to each other, about something that isn't a man.
So, would a LGBT version be, two LGBT people, who speak to each other, about something that isn't a cisgender and heterosexual person (be it other LGBT people, themselves, their careers, their hobbies, whatever)? In which case QC passes multiple times - Dora and Tai satisfy it (by talking about each other), Tai and Claire satisfy it somehow (although Tai doesn't know that), and I can't think of other examples at the moment.
