Now, what WOULD make sense is a superhero LGBTQ advocacy group, where high profile gay heroes do media events and charity work to raise awareness of LGBTQ issues and help inspire people.
Probably shouldn't have Midnighter on that team, though. Not exactly an inspiring public figure.
Aside from that the only reason for an all-gay hero team would be for meta purposes, so the only way to do it in a way that made sense would be to have a team that was in-universe just coincidentally made up of mostly gay heroes, probably have one token straight character.
