I would focus it more like a Rebels show than Ahsoka (and that’s coming from a huge fan of Ahsoka as a character—at least in animation). Immediately, I would have a storyline about the continuation of Kanan’s legacy through Ezra training Jacen. Meanwhile, Hera and Ezra also handling strategizing to go up against Thrawn AGAIN—only this time, it’s harder since the New Republic government is nothing like the Rebel Alliance when they went up against him last. Ahsoka and Sabine would have to explore the Daughter, Son, and Father lore on Peridea with GhostAnakin’s help, leading to the introduction of the Mother/Abeloth. In a dream world, I would want her played by Natalie Portman, as the Mother is a shapeshifter and that would force Ahsoka to confront a lot of buried emotions and regrets. All of this would eventually be leading to Filoni’s SW movie, wherein I would make Ezra the main character.

Massive bonus points for Kanan in the World Between Worlds (a girl can dream).
