Interiors and floor plans would be neat. I'm guessing there would have to be something like those drawn up - how many exterior drawings would there be for the 2 dozen or so ships and vehicles appearing in all the movies?
Multiple orthogonal representations for sure; but it's a safe bet we'll be seeing more than just ship exteriors. Mind you, there's also tons of other hardware items as well - large and small - that would make for ideal subjects for schematic treatment.
Either way, what a great in universe resource this will be.
