Something like this would be great but very time consuming (I can't imagine many of the original elements of what was in it's day a ground breaking set of special effects sequences surviving a reworking of this magnitude).

It would also add to the impression of a major clash between two fleets if we saw more fighting way off in the distance.

The ROTJ battle frequently has something epic in the foreground to cover up that there isn't much going on in the background (other than a lot of cut and paste duplicated ships barely moving about).
