I said some, not 'ALL' . Lights are not a problem. Flying Asteroids are not a problem. Blasting asteroids could pose a problem. Escort ships turning away, major problem. There is not enough time in that scene to make that idea work with the established shot. The executor barely clears the asteroid field before it cuts to vader entering the holo chamber to talk to the emperor. Now, how much time are you going to have to show any escort ship pull off and return to the asteroid field before the scene cuts to Vader?

You would have to make a brand new shot to make that happen, and thats totally unnecessary Just to please the "We just gotta change it because it's REVISITED".
