It’s easy to get Attack of the Clones under an hour. Just redub the analysis droid scene to imply Jango is on Geonosis rather than Kamino and change the crawl to imply that the clones have already been created and the debate is more about whether or not to deploy them. Then cut the romance similar to the Phantom Editor.
The question is whether or not you’d really want Attack of the Clones under an hour.
Expanding upon that, you could have Anakin dreaming of Obi-Wan’s danger rather than his mother’s. He could go directly to Geonosis from Naboo.
