Maybe you could just replace the mountains and/or the AT-ATs, since those would be relatively more stationary than the ground itself. Even if you didn't "replace" the AT-ATs with new model shots (or from different scenes) could the images of the AT-ATs themselves be worked a bit to appear less faded?

this is what's impossible about it. There are no definite points to track to add anything to the background. the camera is moving all over the place .the only way to fix these shots would be for all outside cockpit elements to be brand new. i would need a lot more space than i have available to create a new snow floor to film.

I know, I know... we ask the impossible (or improbable?)...

But Vaderios had a good point in that the outside cockpit shot he uses in his mock-up comes from the following scene. I think what V was saying was you could possibly use THAT shot for the cockpit view.

In regards to the camera moving all over the place, you have stable cockpit shots you could use for the cockpit element. Rather than keep the original shot or any part of it (such as blue-screening the mock-up background onto the original shot) maybe you could do one of 2 options:

(1) take an earlier cockpit scene (Luke's strafe of the first AT-AT or inside Zev's cockpit during the search) where the camera is stable; delete the external image and replace with the new background. Afterwards, any sort of camera shakes could be added to recreate the original shot.

(2) take the new mock-up shot but excise the cockpit. There were shots from inside Zev's cockpit when he was searching for Han and Luke where all we saw was the terrain. You could in essense put the camera right outside the cockpit window so the only element to mess with would be the outside image... as well as add the shaking and other elements afterwards...
