How about a new Knights of the Round Table? I'm thinking of an organization than answers directly to Queen Elizabeth or whoever is the head state in the UK. They consist of either known superheroes, secret agents, and a few wizards. Main objective is to keep the United Kingdom safe, but will cooperate with other superhero groups when necessary.

The organization itself might be secret and the main problem might be why haven't appointed the actual King Arthur as their leader.

I've got an idea for a comically bad heroic team based on american football, if you're interested.

Sounds like something from Kill la Kill. It also kind of fits when you get into the really silly stuff in comics and anime.
