Emphasize the Obi-Wan/Anakin friendship and avoid the space-prophecy shit set up in TPM. I’d encourage him to make the clones the bad guys and have the stormtroopers just be an army of normal people recruited to fight them. I’d also have Bail Organa and Owen Lars play a bigger role in the drama.
EDIT: I’m also fine with the Padmé and Anakin love story but it shouldn’t be a Romeo and Juliet forbidden love thing.
