Maybe revealing Obi-Wan's biological parents revealing Ezra's mother is his niece since that would neatly explain a descendant of Obi-Wan without upsetting anyone wondering why Ben didn't train them to help protect Luke?!
Maybe a Magnificent Seven movie set on Tattooine except he's the eventual sole survivor staying out of sight but helping thwart an attempt to cause the Tusken Raiders to join into an army to wipe out the residents similar to what Darth Krayt did in legends before Disney took over the Star Wars comics?
I haven't read it yet, but I've heard the Kenobi novel is basically the Magnificent Seven on Tatooine.
