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.
I think Two-Gun's status got some additional credibility from the She-Hulk storyline, where somehow time was broke and she got to rescue one time traveller from the TVA and chose "the Avenger" (meaning Two-Gun). This saw Two-Gun brought forward to the future again when he appeared as a regular in her series. It shows at least she considered him a fellow Avenger.
