Here’s an idea I’ve been toying with for my short film edit which I feel may more appropriately belong here.
What if, instead of the dreadful frankenvader scene from III, we repurposed footage from Rogue One to signify the introduction of the suit? Krennic may be out of place, but the viewer would just quickly assume that he’s some imperial lackey overseeing the reconstruction of Anakin.
I was also thinking a sharp editor could replace the hooded figure from the beginning of the Vader scene with The Emperor. Technically speaking if you rotoscoped Palpatine’s face into the hood, and then drenched the scene in contrast and dark to cover up any remnants of altercation, you could probably get away with it.
My edit is dialogue free at this point, however, so a standard feature length edit may have some difficulty implementing this idea.
