3. The Rebel Alliance
This was rumoured to be in the works a while ago, as a Band of Brothers type mini-series. Sadly, this was never finalized. Now that Disney has the reigns there is the ability for production value, distribution, programming, and exposure. Disney also has the added benefit of nothing being restrained by outside influencers because of how large they are. If anyone could pull off this monumental endeavor, it would be the creative minds at Disney.
2. Obi-Wan
The first three Episodes of Star Wars should have been Obi-Wan's story, and not a split between him and Anakin. Obi-Wan was the man who let down his late Jedi Master by allowing Anakin to be corrupted by the Dark Side, and there is a tremendous amount of regret that sits with this. His spin-off should be a film that focuses on his life in the desert as he tries to mend his own psyche. It should show his dealings with the Sand People, how he comes to know the villainy in Mos Eisley so well, and how he was able to develop the ability to live everlong in the Force.
