What problem do you foresee with a multiblock of structured grids? The memory overhead of vtkStructuredGrid? It seems pretty minimal to me compared to the b-reps CAD packages use and the multiblock dataset need not be flat... it could be a bounding box hierarchy for fast culling of irrelevant patches.
