I get the idea here, but there are a couple of issues that need to be resolved for this to work. First, Scariff and Tatooine require some travel time. We need to perhaps see the Tantive IV in hyperspace. If someone could superimpose the tantive IV and a star destroyer over the Enterprise being shot at in warp by the Vengeance (ST:ID) that would help with the transition between the two planets. Second, the visuals are just too crisp in Rogue One. If this is an intended edit, the RO footage needs A LOT of grading to simulate a 70’s era film.
