I have been thinking about how you could truncate the plot ever since NFB posted his opening test, and here’s my take on it. If I were to do an edit, I would prefer to keep scenes with the strongest and most interesting character interactions and moments. And I would rather cut or remove stuff that raises questions regarding continuity in relation to the Saga films. My exception to this would be Obi/Leia relationship. Sure, it could bring up questions about how much Leia really knew about Obi-Wan in A New Hope, but I think the strengths of their character interactions in this series outweigh those potential issues, so it is worth keeping.
After a NFB-type opening, you could keep Owen confronting Ben, but cut everything with the Inquisitors and the runaway Jedi on Tatooine. You could keep some of the Leia stuff and her getting kidnapped, or just show Bail calling Ben for his help.
It seems some people suggest cutting episodes 2 and 3, and having her being immediately taken to Fortress Inquisitorius and have them rescue her. Personally, I would rather keep 2 and 3, and completely cut the Fortress Rescue. Because 1) It is too reminiscent to the Death Star rescue, and 2) Some of the stronger Ben and Leia moments are their interactions in 2 and 3. I would like to keep the scene at the end of episode 4, when Leia and Ben hold hands, and move it to when they escape Jabiim in episode 5.
This also gives you a lot of wiggle room with how much you want to keep of both Vader duels. You could keep their first duel, or have Obi just run away and/or get burned, or have him go through the tunnel and escape with Tala and Leia to Jabiim. Kenobi getting burned has no effect on the story beyond him being in a bacta tank very briefly, which could be removed if you didn’t want to keep that. I personally feel like the logic doesn’t work for the set up of their second duel (why couldn’t the Star Destroyer continue to follow the transport?), so imo, that whole duel could be removed without it really changing anything. I think it would be cool to rework that duel into a short nightmare Ben has while he is in the bacta tank, then you wouldn’t have to worry about why Obi-Wan leaves Vader alive, or try and rework the duel where Vader leaves Obi-Wan buried under rubble. A lot of the force stuff in that duel just felt over-the-top to me.
And then you could have Reva “die” on Jabiim and remove all of the stuff with Luke, Owen, Reva etc. in episode 6.
Would it work if the kidnappers weren’t hired by Reva, but once they realize he is a Jedi, they contact the Empire for a reward and then the Inquisitors show up? Reva could still post the planet-wide bounty after they arrive if need be. One benefit to this is that you could make trims throughout so the Empire/Inquisitors never know there is a connection between Obi-Wan and Leia/the Organas, or that Leia is specifically the girl he is traveling with.
Anyway, just food for thought. I feel like this general outline would give someone quite a bit of flexibility.
