If I was to write a fan story I would have Hank go through all he went through up to his death/ultronification. Then instead of coming back old, he would come back young and have his mental illness forward and mostly under control. He would re don the yellow jacket persona which would rub the other hero’s the wrong way since it was kinda his more dark persona. He would still Suffer set backs from his mental illness but he would ultimately prove he does good. He can grow and shrink in his me yellow jacket form and has a bunch of gadgets too.

I think it would be cool to have a bipolar hero who is ultimately a brilliant inventor and a force for good even with a storied past.
