I'd be up for Filoni taking over from Kennedy if that means that he's too busy with the business side to screw up more of the creative side. I mean, he's done some good work. The Mandalorian is really good so far, and the best episodes of TCW can be amazing. But the bad episodes of TCW are some of the worst official stories in the franchise, Rebels was a mediocre kiddie cartoon and Resistance is ever worse.
Now, Lucas can be blamed for some of the bad stuff in The Clone Wars, but Filoni is the one responsible for Space Aladdin and Baby's First Order shows. He definitely needs to be reigned in creatively, maybe just used as an idea man but with no actual authority (because he can do great stuff, he's just been doing less and less good stuff as time has gone by, kind of like Lucas, actually). But, if taking over for Kennedy means he has authority but isn't working on the creative side, I suppose that would work.
