There's the snag, we don't have much to play with there, in the film as it is we don't see the crew of the Falcon, we just hear them.
You could play up the familarity of the situation by moving Threepio's "Here we go again" there (but set it inside the Falcon being shot at) and let the models do the rest.
It would underline how relentless Vader is up until that point.
It may be possible to replace Nien Numb for Chewie for a few seconds of the Falcon cockpit and maybe a Star Destroyer bridge shot.
The sequence needn't be very long, just enough to remind us that the situation for Luke hasn't changed much in terms of his relationship with his father.
A wee challenge for the video mockup gang perhaps?
