I liked it more than the TVA one. His design was beautiful and I while I doubt it, I hope it's something we see in other comics. I also liked that the writer understood how kinetic energy works, hehe. Gambit charges, but he could also "uncharge". The more abilities he has, the happier I am.
What I didn't like much is that the story sounds too similar to G99, and he wasn't given those powers, he was born with them. So, this is a what if too similar to something that has happened. I feel people tend to forget how powerful Gambit was meant to be if he hadn't got rid of his full potential, but he still managed to use it back then. Super powerful Gambit ain't nothing new.
Aside from that, it was ok. The dialogue? I have zero expectations for dialogue in current day.
