Do you have a minimum age requirement for characters?

I have a few ideas, yet some involve canon characters that have either traditionally started their careers as teenagers or their best-known intepretation is that of a teen. (One character I'm considering is technically so young in the comics I'll have to age her up so much that she'll be an OC.)

You could age a character up, make an older character young again, there's a few different ways to rework a canon. Jakeem Thunder is usually one of the younger members along with Stargirl and Shazam's alter ego Billy Batson. Then you've got characters who debuted in the 40's who're still around.
