Getting back to the issue of scale, I could be wrong but I don't think this is any smaller than the other dioramas. Star Wars dioramas have pretty much all been 1/9 scale. If you accept that Leia would be around the same height as Jabba when standing normally on the base, that would make her about 7" tall (the whole diorama is 7.5", but I assume that's including the base). Carried Fisher is 5'1" which would be just under 7" tall in 1/9 scale, so I'm guessing this is 1/9 scale or pretty darned close.
