I have an idea, I don’t know if it would work in practice. I think it would be interesting to start the story with some of the clone wars scenes shown in the series.
I say this because Ahsoka, in theory, starts in the series with a conflict, right? However, the public only discovers that she is conflicted in episode 5. Personally, I think that focusing on the character’s development is more interesting than the quest to prevent Thrawn from returning. This is Ahsoka’s series, after all. Showing her conflict right away would serve to introduce the character in a more appropriate way than fighting robots in a temple, serving to tell her personal journey since the beginning of the story.
That said, I think it would be interesting to show some of these scenes as a dream of Ahsoka, and show her waking up from this dream in that scene with Hyuang on the ship, and only after that begin the plot of Ezra/Thrawn’s search. Later on, when Baylan knocks her into the water, the focus would be on the world between worlds sequence, where she would get the motivation to move forward, leaving the conflict behind.
