Having the Morgan fight would also be nice because of the Thrawn reference, it would give us an idea of what Ahsoka is up to early on. But I see why that is difficult Structurally.
Just throwing out ideas: Maybe this is a 2-movie edit?
One that intercuts Ahsoka with Mando, culminating in them finally meeting and working together at the end. (Opening fight scene of Ahsoka attacking the city would also need to be reinstated)
And then one that shows Bobas journey parallel to Mandos, culminating in those 2 meeting.a bit less concise, but maybe it would give the audience more room to breath.
Intercutting Ahsoka with Mando isn’t an option unfortunately. There is only one Ahsoka-only scene that occurs before Mando arrives on Corvus. Meanwhile Mando has arrived on Tatooine, killed a Krayt dragon, walked to Mos Eisley, evaded the New Republic X-wings, travelled to Trask, headed out on a trawler, met Bo Katan, captured an Imperial cruiser and then traveled to Corvus.
Having the Ahsoka v Morgan duel now feels almost essential in light of the Ahsoka series, but I’m really trying to stick to a single movie for this edit so I’ll have to see how it all feels.
I have toyed with the idea of ending this movie with the capture of the child, but it would be a crime not to have Luke’s rescue as the final scene.
