>>88808807I would have completely revamped the story so there's actually a consistent arc between seasons. Of course that would mean that they would have had to plan the show out ahead of time, and there would be more episodes per season.
The Red Lotus becomes the main "villain faction" for the entire show. Their goal is the same as before, to destroy the Avatar and end the cycle. The Equalists are actually secretly run by the Red Lotus. Amon is an agent of the Red Lotus, and he really did get his powers from a spirit (Vaatu). Unalaq's role is similar to the original except he's a lot more sympathetic, his role in the Red Lotus is more clearly defined, and he doesn't fuse with Vaatu. Zaheer becomes a recurring antagonist similar to Azula. Kuvira becomes involved in a long-running Earth Kingdom subplot which culminates in the formation of the Earth Empire.
Book 1: Starts similar to the original but Korra doesn't stay entirely within Republic City, there's no sports or love triangle plots, and it ends with Korra losing her bending and her connection to previous Avatars (there's no Aang deus ex machina).
Book 2: Korra must travel the world and re-discover her past lives. Each episode somehow involves a different Avatar. Wan is especially prominent and his plot ties into the main story.
Book 3: With her Avatar powers regained, Korra must now deal with both the Red Lotus and the newly formed Earth Empire, and find a way to forge a compromise between all sides.
Book 4: Doesn't need to exist.
And in this show the Fire Nation would appear for more than five seconds.
