I loved the idea of targeting a New Warriors-esque team using roughly the same dates as the characters' debuts. I'm going to try that now, only with a team of classic Avengers members. Each corresponding DC hero will have debuted the same year as that Marvel hero. I'll try to line up powers/abilities/personalities as best as possible, but year of debut is the motivating factor here.
