I'm not a big fan of ash taking down TR/Giovanni. I feel people only want that because he is the MC, instead of any actual build up. Tbh, it seems ash doesn't really care about TR. Other than the TRio constantly going after Pikachu, he seems to not really care what TR as a whole does when they aren't after him. He is more connected to the TRio than TR as a whole.
He only met Giovanni, I think once or twice. Idk I just feel like it won't be satisfying. Besides I feel like a villain like Giovanni isn't gonna be used effectively when going against ash. I can see him spouting the usual "people and pokemon are friends, blah blah" stuff like he did with lysandre. Not actual personal conflict. Just a generic villain he would blank out
I admit it's for this reason I feel they'd either have to do something rather clever with Giovanni to add some sort of personal conflict for Ash (maybe a play off past events similar to Rainbow Rocket, showing all the effect he has had on the past) or alternatively they would have to do the arc mostly for the TRio's POV.
Like I feel like an ideal final arc for TR would be them snagging Pikachu....and running for it. No gloating, no stopping to celebrate, they just tail it in their balloon all the way to HQ, evading all attempts to stop them.
They finally make it to Giovanni's office and, likely on the verge of having a heart attack from finally doing it, reveal they DID IT. THEY GOT PIKACHU. And da boss will say...."Oh a Pikachu, yay, I guess. Well put it with the others and get back to work."
The door slams behind them, and the TR are left baffled. THAT was it. Their big moment of vindication. The disallusioned TRio are then left with the choice of taking this as their big lot in life or helping Ash get their worthy arch rival back.
As someone who experienced Team Galactic for the first time in the Arceus special some month ago, I have to say I liked how competent, and for the most part professional, or maybe just not comic relief-like they seemed, even when they were losing.
It was like they were anti-TRio / BW! competent TRio.

Saturn being voiced by Nami (Akemi Okamura) WAS kind of both weird and interesting.
Actually I feel it might be an even bigger hot take to say I kinda prefer the games' more whimsical take on the other villain teams.
EVERY team in the anime besides Skull truthfully feels like that, an sinister anti-TRio with none of their silly or sympathetic qualities, despite often having just as grandoise a thematic as TR. Like I get the elite bosses should be menacing, but even the grunts tend to be generically stoic. I feel it limits their potential, they're just another mean plot device villain, an army of near cyborgs, which we all know don't really bounce off the heroes.
Even if they wanna do their own thing with the villain teams, it would be nice if they did more variation. Like Galactic being the big menacing villain arc sure since it was probably the best handled case of that, but maybe keeping Cyrus' more developed motive, and the other villain teams being all sorts of other dynamics besides 'shady sinister guys'.
