You know, there is such a good plot twist/lore twist that Disney could do with Star Wars with the origin of the Jedi and Sith, but  doubt they'd take it.

AKA Sith were once rebel good guys and Jedi were illuminati bad guys. Imagine that twist and what you could do with it. 

Also WTB Jedi/Sith hybrid. Reven isn't canon :(
