One of the ideas I had was that in (in the Marvel and DC universes, anyway), being a side kick or a teen hero is kind of like forming a garage band. You do it for a while and then maybe one of the people goes on to actually be a musician, but most people don't -- they go off to be accountants or welders or lawyers.
The premise I thought of was that a group of young adults who used to be the Teen Team are called together by the one of their member who has become a wanna-be TV show producer. (This gathering doubles as their Christmas reunion, anyway.) This member's secret agenda is to get everyone to sign off on having their likenesses used in a show based on the Teen Team (he's already sold the show idea, he just has to get the paperwork filled out). Everyone else thinks it's a reunion.
And bad guys get involved with old grudges.
There's certainly a chance to talk things out ("What? It's just bookkeeping trouble? I can handle that for you!") with the villains, and maybe hide things.
