I’d love it if Maul and Ben ended up as pals and Maul ended up being killed by the Empire.
I think Disney would likely omit Maul, to keep “film only fans” from getting confused. A resurrect or continue on with those characters from the past in the New EU, but keep them out of the films type deal.
I would like to see a completely stand alone story, set perhaps 5 years after Episode III, that starts off on Tatooine with Obi-wan and Owen arguing about Luke’s future. Someone then finds out about Luke, and tries to escape and inform the Empire. Obi-wan then has to hunt this character down and prevent the Empire from discovering Luke’s existence/whereabouts. In the end, Obi-wan returns to Tatooine and Owen thanks him for stopping those events. But Owen is still too stubborn to let Luke go train with Obi-wan.
