Sounds like fun!
Maybe you could use TFA Restructured as an example of a collaborative edit - I personally had a blast working on it with Hal and Ridley and the many others who contributed. The Leia deleted scene and the Star Destroyer over Maz’s castle were both areas that simply couldn’t have been done (or done well) without everyone working together.
And of course if you’d like to use any TFA:Starlight materials feel free.
