It'll have to stay for a little while; as far as I'm aware, that building houses the only public bathrooms on the Lower Lot. If anything, the building will probably undergo a process similar to Mummy Treats/RotM Lockers: keep the function the same, but redo the floorplan. While the path by Transformers is very open, I'm not sure the pathway by the bathrooms is wide enough to be an actual thoroughfare.
