But the thing is, to me, it's just not the JSA without some of the core characters, especially Green Lantern Alan Scott and Flash Jay Garrick. And, yeah, I've always liked Wildcat too.
Every adaptation is its own entity, its own reality. What matters isn't whether it's similar to something else, just whether it's good on its own terms. I've never cared about much Dr. Fate or Hawkman in general, but I liked these specific versions of them.
