I’d be open to your idea, but I wasn’t planning on adding or altering any other shots. Vader establishes moments before the scene that the Falcon “has just made the jump into hyperspace,” so I don’t feel like an added establishing shot is necessary. Stylistically, ANH never depicts ships entering or exiting hyperspace in exterior shots, so I don’t have any problem with leaving everything else as is.
Except for when we see the Falcon disappear into Hyperspace in an exterior shot. Or do you mean where we see a ship transition into hyperspace in an exterior shot with the starfield giving way to the tunnel? Has that ever been done?
