Given that Empire and Wrath of Khan's effects were done by ILM in the same era and Battlestar's were done by John Dykstra, who was on the original Star Wars team, it makes sense that the visual "solution" for these explosions and debris would look similar. I'm sure Ady could fix it but it might be a really big pain and I'm not sure if that is really a "Mistake" so much as a period effects limitation and given that idea, should it be a priority area, or simply something that is corrected with a bigger explosion and more debris to "sell" the complete disappearance of the bridge module - which I believe was the intentional choice of the filmmakers to show how deadly the asteroid field is for any ship, even the massive Star Destroyers.
