Version 3 now completed and available as 1080.mov, mkv and Blu-ray.
In the end I didn’t re-instate the battle at the Corvus fortress. It never felt a necessary part of the story and details the plot. The movie runs so much better without it.
Instead I’ll slightly alter the Mando-Armourer dialogue in EP3 regarding the beskar spear. It doesn’t need to have come from a Jedi.
