i'm not sure it is necessary to have his shuttle in as we already know he is getting one from the dialogue, but a scene of the star destroyers is required to at least bring the viewer's attention back to the fleet, so thus the shuttle makes a bit of sence as just something to catch our attention, and then maybe to remind us who the dead guy is!
so i think whatever shot you use should contain the key elements, ie the superstar destroyer and (probably) a shuttle. i wonder if you could use a similar, but far smaller, version of Vader's shuttle approaching the DSII, ie
[FRONT OF SHUTTLE] -----> [REAR OF SHUTTLE APPROACHING DSII (or reimposed executor)]
if you flip the scenes horizontally and change the speed and distance it could be disguised nicely and save you working on any nasty CG.:)
