@Jim - I definitely want to keep the lobby and basically lose the extraneous building behind it. I expected that there might be a plug / terminals to move.
@Donald - Thanks so much for those pictures and measurements. That helps tremendously. I like the WS theatre building better than the Atlas, but the animated sign is really what draws me to the Atlas building. Looks doable if i want to chop the building to about 6" or thereabouts.
Of course now I'm wondering if there's something I could do to the Woodland Scenics building to give it some light animation
