Eliminate the AT-STs? That doesn't make much sense. They may be in only two shots, but it sounds like you're deleting them for deletion's sake. The Empire does have 'variety' in their forces.

Why doesn't it make sense? Check the scene where you see the one walking in the background after Luke has fallen from the AT-AT. Where did it disappear to? you should see it in the following shots but it just mysteriously vanishes. So i'm not just deleting them for deletions sake, as you put it. Agreed i may be able to keep the one shot earlier on, but change it height, but the one with Luke has to go for continuity sake
