I wonder if this would be possible to the "cloud car fly-by":

In the fly-by, modify the top of Leia's building so that only a small tower on the right-most tip remains.
Leia's window would then be facing left in the fly-by shot and the large bulbous building need not be changed here.
In the shot with Leia moving about, make the bulbous building slightly shorter to align the platform's height to the building's facade. I think that it would be easier to change it here than in the previous shot.
In the shot with Leia moving about, open up the perspective to how it was in the OOT by making Leia's window smaller and move it to the right. (This was discussed a few paged back)
This would reveal buildings to the right of the large bulbous building. I think that it would work to reuse lower-resolution sources to fill this space. The distance to the (old) buildings would be quite far, and we can explain the blurry pixels as "atmospheric haze"

What do you think? Should I paint a mock-up?
