I think it would be nice to see heavy war rifles in Endor. Like the one Han uses in the DS in ANH, which was taken as a model for all the PT clonetrooper guns.

Might not be a need for interior corridors of the DS where the Empire is clearly in numeric advantage, same applies to Bespin, but i think they would be logical in Endor. Actually it's not that much a size issue but a weird thing nowadays to see that strange shooting pose from the sixties and seventies. Shooting from the waist was cool for spies and cowboys, but not for a trained army.
