Could This Film Be "Fixed" By Sound Editing Alone?

I recently rewatched the prequels and although some things about this film cannot be fixed (mostly continuity stuff like Qui Gonn's existence for example), I started wondering if you overdubbed the voices of Jar Jar and Anakin - replacing them for the entire movie, and additionally replaced the dialogue at some points - whether this movie could be saved?

Going further, Jar Jar is CGI, so presumably the entire character could be replaced by something less stupid. But even without that, just making his voice less irritating and racially problematic might be enough.

Anakin would need more work and potentially changing the dialogue might be harder. My biggest annoyance is that he isn't the "great pilot" Obi-Wan had cracked him up to be in ANH.

I don't know why but for some reason on this run through it stuck me that when he's giving his "whoops!" and "oh oh..."s when taking off in a spaceship (for the first time!) that maybe his lines were supposed to be delivered sarcastically and he knew exactly what he was doing.

He does after all set it off moving, closes the cockpit and starts gunning the battle droids. Maybe if the dialogue was slightly altered it could make this work a lot better, rather than the kid randomly hitting buttons and blowing everything up that we got...
