Hey, it would be funny if Owen actually is Obi-Wan's brother anyway. It would be a really wierd coincidence, especially when we're talking in galactic terms, but it could work.

Until I came across the reference to the other Owen in the Jedi Apprentice series, I liked to pretend that, if only to give a bit more meaning to the line, "You were my brother, Anakin!" If the Kenobi-Lars relationship had been kept, they would have actually been stepbrothers. Unfortunately, Obi-Wan's family supposedly lived on a grassy planet and were fairly wealthy. Neither description fits the Lars family. Sucks, don't it?
