Korra is great. Bending is similar to using the Force.
I would've like to have seen more new ideas and unexpected perspectives on the series.
In fact, that's where I'd take Todd's idea about the droid rebellion. Off the top of my head, The Maker returns in the form of a mysterious entity who can take over any and all droids (except for C3P0 and R2D2 for a mysterious unknown reason). He (or it) uses his droid trooper army to overcome all resistance. He claims he wants to bring peace and harmony to the galaxy by ending the reign of Force users. He argues, persuasively, that the war and turmoil that the galaxy has endured for centuries has been the direct result of the cycle of conflict between Jedi and Sith.
"The Force exists, but it needs nothing and wants nothing. It has no dark or light side. The only evil lies in those who would twist it for their own ends, whether they believe themto be righteous or selfish."
As the Maker converts the galaxy to his way of thinking, Princess Leia's children must flee the Maker's forces. Jacen (or Ben) Organa-Solo allows himself to be captured so his sister Rey can escape. He's thrown into a special prison for "Force Users" where he meets Sith apprentice Raxasha (basically a female Darth Maul) who tries to kill him before she's incapacitated by the droid guards.
Meanwhile, Rey is almost captured except she's rescued by a force user with more power than she's even seen. He takes her to a secret forest moon hideaway in a ship that has no navigational system so she has no idea where they are going.
"No one can travel through hyperspace without a navigator."
"Apparently, you're wrong."
"How do you know where you're going?"
"I never do, but I always end up there anyway."
"Well, don't blame me if we crash into the side of an asteroid!"
"I'll try not to."
Of course, the strange old man turns out to be Luke Skywalker, Rey's uncle* who disappeared not long after she was born. He pulls a Yoda on her ala-
"You know too much. I can't teach you anything."
"Please, I don't know anything!"
"Well, I guess that's you first lesson."
Back on the Maker's ship, he has brought captured Princess Leia to persuade her to join his cause. He knows that her support carries more weight in the galaxy than all the politicians and warlords who've joined him. He brings Jacen and Raxasha to them and fits them both with inhibitors that attach to the base of their skulls and prevent them from using the Force. The Maker tells Leia that he now has no reason to kill her son so long as she agrees to support him as the public face of his crusade.
Despite Jacen's protests, she complies and tells the Galaxy that Force Users must be hunted down and stopped for the good of the realm.
Back on the moon, Luke's lessons to Rey sound very similar to the Maker's arguments, but from a different perspective.
"The Force has no Dark Side. It doesn't need or want like we do. No one needs to learn how to use the Force. You need to learn how not to use it, so it can use you."
"But if it doesn't need or want anything, why would it use me?"
"That's a good question. Let me know if you find the answer."
"You're crazy, old man."
"There is more to the galaxy than good, bad, yes, no, love, hate. Rey, there will always be another way."
Back on the Maker's ship, Leia's servant and best friend Viranna turns out to be a trained Jedi. She frees the Princess by using the Force on her droid guards. Together they free Jacen from his prison. He insists she free Raxasha as well. Suspicious, the Sith refuses to go with them unless he explain why a Jedi would help her.
"The enemy of my enemy-" he starts.
"Is not your friend," she finishes.
"An ally, then?"
Raxasha has little choice but to accept his offer, for the time being.
Leia and Viranna hold off the Maker's forces, but Leia has to remain behind to give the others a chance to escape. In the biggest reveal of the movie so far, Leia uses the Force and proves to be almost as powerful as Luke. To win the battle, the Maker has to incinerate the entire building.
Far away, both Rey and Luke feel Leia die. They grieve and Luke tells her that Leia was his first student. She was strong in the Force but she stopped training when she felt the pull of the Dark Side.
"Even then, she knew it better than I did. She was stronger than any of us."
Rey insists on returning to face the Maker and save what's left of her family. Luke, like Yoda did for him, tells her she's not ready.
"You'll never think I'm ready," she tells him. "Because you'll never be ready to let me go."
Despite not having a navigator, Rey prepares the ship for departure trusting the Force will guide her. Luke joins her.
"You must continue training, Rey."
"You can't make me stay."
"I know, so I'm coming with you."
Meanwhile, Jacen and Raxasha barely escape the pursuing droid soldiers. They are forced down on an deserted planet, and Raxasha uses Jacen as bait, he's wounded but without the inhibitor, she easily manages to destroy their attackers. With Jacen unconscious and vulnerable, she considers killing him too, but instead she uses the Force to pull the inhibitor out of his neck.
"The enemy of my enemy-"
She feels the barrel of a blaster against her head.
Chewbacca stands behind her with his crossbow blaster ready to fire.
"Take it easy, Chewie," a revived Jacen tells his old friend, practically his uncle. "She's a friend."
And so it would go, you'd have Rey discover that Luke was her real father and he left her with Rey and Han after her real mother died, and he had to leave to find the source of the disturbance in the Force. In the end, Rey faces the Maker and defeats him by not using the Force, the true identity of the Maker would be revealed and Luke would sacrifice himself to destroy the Maker's superpowerful warship deactivating the hold he has on the droids of the galaxy.
Jacen and Raxasha would fall in love and, with Rey, begin the work of finding and training Force users to find their own way as neither Jedi nor Sith.
Just a quick sketch for an idea.
