Gotcha. Yeah, he's a kid in high school in canon, so I'd be more than good with aging him up to early-mid 20s or something less, uh, weird. :|b As for AU-ing into a superhero, that would be fun! Or there's always weird time/space/jamjar-esque ~shenanigans~ that could put one of them in the other's world, if the whole fish-out-of-water and scenario was a thing you were interested in.

Either way, I'm not picky!
