Very cool job on the covers!
Not sure if I'm too late to the game... but I do have an interesting item that can maybe help?
I have a poster that was most likely from a video rental store. The only other time I saw this poster was on eBay, when the seller claimed all copies of this were always folded (apparently mine wasn't).
The poster showcases the VHS covers from the trilogy, and they look very sharp. The entire poster is roughly 2 feet wide by 3 feet tall. The individual VHS covers measure about 6 inches wide by 12 inches tall.
I need to re-frame the poster because the heavy paper causes it to slip down in the frame. I suppose I could scan in sections of the poster if needed. The poster is in very good quality and all artwork and text appear to be quite sharp.

Here's a quick photo of the poster I snapped with my cell phone:
