I still wonder if people would want Darth Maul as the new Sidious, a femme fatale apprentice. and a midichlorian story nobody liked that in the prequel. The story of the Whills, Luke training younglings.

The only net positive I can think of is a successful Jedi Order and New Republic government. With Leia as chancellor. And Luke replacing Yoda as the head of the new order.

I just don’t see Darth Maul as a threat to Luke’s authority and power. Not when Obi-Wan dispatched him so easily in Phantom Menace. Any rebellion of Stormtroopers and New Sith shouldn’t be too hard to deal with. With hundreds of Jedi and a giant galaxy wide government.
