Yep - a pretty much spot on list in my opinion. I find is hard to count Two-gun and Nova, but I have to give you credit for giving the swerve to the GoGs, Prince of Orphans and another Nova. I have literally never heard of Flux and Victor mind you. Would like to forget Machine Man, but I think he has to be counted and I did not spot him in your list. Could be Hickman has already retconned Abyss and Ex Nihilo which would be no bad thing. (My) jury is still out on anyone coming in on the new Mighty Avengers.
You are correct. I was thinking today I forgot someone.
