Yes please! I'm definitely down with that Justin!
To be honest, I could care less about the Ep. 3 play value, though a dual set for both movies would be cool. I'd just love to have the "opening corridor/hallway" with door that gets blasted open at the beginning of ANH. I'd love to setup a diorama of that opening scene, since I'm way too untalented to customize something like that myself. I remember someone doing a kick ass custom of that a while back, and even had it on display at C2 in Indy. Was that Niub Niub, or someone else? Don't recall anymore.
I suppose an additional attached room where Vader chokes Antilles, and the corridor where Leia's taken captive would be sweet too. One big playset with all three of those areas for $30ish, or 3 interconnecting sets for $10 each. Whatever. Just make it!
