OK, here’s my ROUGH outline of the Rebel reunion, a blueprint of what can be done with the existing footage.

Main changes:

Simple “I how you one” dialog right after leaving Tatooine, and we move to the rebel fleet
Luke comes in early with the generals
Luke is shown as part of the Resistance leadership.
Han’s team is already assembled

Yes, sound it not seamless, Luke is missing from some wider shots, etc.
But it might be useful for IlFanEditore 😃

About the crawl I don’t understand “With the support of his allies”. Luke is supported by his friends.
There’s nobody else helping 😉
