This model file size is pretty small and the quality is pretty good, and the model fits your building size of 2x2 perfectly.
Yes, absolutely. It looks really good and would fit perfectly with a machine made to customize items.
I considered it and thought that it wouldn't fit. Now that I look at it again I think it would work pretty well.
Done.
