I honestly can't think of a productive use that is financially feasible for a building as big and in as poor shape as MCS, especially when you consider where it is.

I think they should save the entire lower facade, demolish the building, and incorporate the facade into the new transit center in south New Center where the Amtrak facility is. There has been a long time plan to build Detroit's functional "union station" there. I dont see any better way then to incorporate the architectural detailing of Detroit's old "union station"
