As long as it is not too gritty (Star Wars must be fun after all), this seems quite good. It should definitely not be called Star Wars; seems like The Adventures of Luke Skywalker would be more appropriate. I also would prefer to retain the notion of a benevolent Republic decaying into a despotic empire.

Let me add some lore from my own Star Wars timeline I did a few years ago:

THE CLONE WARS: 3 separate conflicts that taxed the waning strength of the Old Republic. Each one more vicious and destructive than the last. These involved the forces of the Republic against the Clone Masters and their allies; the dreaded Mandalorians. The end of the wars saw the utter destruction of the Clone Masters, the destruction of all exisiting cloning facilities, the banning of all cloning technology, and the absorption of the Mandalorians into elite special forces of the Empire (often attached to Sith Jedi-hunter squads).

OBI-WAN KENOBI: A hero of the last two Clone Wars. A great Jedi and brilliant general, it was he who formed the famed White Legion that was instrumental in several key battles that turned the tide of the wars against the Clone Masters and their allies.
