There's a lot of room for various Jedi in that time frame (Baylan!), so they could have a main book following Obi-Wan and Anakin, another following some other Jedi (Windu is an obvious choice, but there are a lot of options), Jango covers the bounty hunters, then a Dooku/Ventress book or a political Sheev/Padme book (it's unfortunate that Anakin can't run into Padme in this time frame, so they'd have to do some location gymnastics if they did a big event). They can't have a huge event that makes you wonder why there wasn't a Republic Army formed before AotC, but there's a lot of galaxy to explore and just tell fun stories
