It would be interesting to see Owen as Anakin’s brother and a soldier fighting alongside him in the Clone Wars. We get a hint of military know-how when Biggs says: “Your uncle could hold off a whole colony of sand people with one blaster.” In one of my prequel ideas Owen and Beru served in the war but left for the Outer Rim when the Republic began to transition to the Empire. They had no stomach for a war that they didn’t believe in, and tried to get Anakin to come with them but Anakin would have none of it, deciding instead to follow Obi-wan. They end up going to the Outer Rim with a fleet of deserters and refugees, so Anakin couldn’t have found out where they ended up if he tried. Eventually Obi-wan and Anakin part ways, and Obi-wan takes the newborn Luke in search of Owen. He finally finds them on Tatooine after months or years of searching.
