Here’s an idea:
Have the conflict of Attack of the Clones revolve around the Separatists having a weapon of mass destruction (The Death Star). Dooku escapes Geonosis with the Jedi knowing he basically has a nuke in his pocket. In the original film Dooku escaping means nothing, he doesn’t have Obi-Wan locked up in Carbonite in his ship or anything.
This plan would require the dubbing of a few characters, I think.
