I actually considered having the beam travel through Hyperspace in this shot, after deleting the Star Destroyer, but I don’t know of an easy way this could be done.
To make the Falcon exiting Hyperspace I blended two shots where the Falcon was in a similar position in each, so the best bet would probably be to find a shot of something else going through hyperspace at a similar angle and replace the ship with the beam. If the camera movement was similar enough in both shots, it might work.
