I've thought about this same issue myself. One of the many WWG projects I've considered is a complete village. While VillageWorks as is would be perfect for a skirmish game on the streets of the town, etc.; just using the buildings as obstacles and terrain. For RPGs, my obsessive nature makes me want a complete-to-scale layout. If the party ducks into the shop on the corner to evade the guards, I want to be able to lift up the building and voila! There's the floor plan of the store underneath.
I realize that an entire village -even one with just a handful of shops, a tavern, and a scattering of huts- would take up some serious table-space, but it sure would be fun to make and play.
