Not at all, but since we’re having fun, gun to my head, i would let the Emperor say Vader’s line in the final battle so it sounds like “The Force is strong with this one, my apprentice / Lord Vader” or smth. to that effecr, so they mirror Obi-Wan’s advise “Use the Force, Luke” and we would immediately know, that Vader holds a similar mentor-relationship to someone. Would be a real nice, brief mystery up until “Empire Strikes Back”. That said, I think even that would overweigh the on point-editing and storytelling of part one, opening up a new plot-thread in the middle of the final battle, where our focus lies on our heroes surviving and destroying the death star. But hey, we’re having fun here.
