FYI, since none of those are rigged (IIRC), you can take any of them, put it together in DS, export as .obj, then import the resulting .obj into Poser. You can do it all in one go if you don't expect to swap anything around, or you can do it in pieces.
It'll take 45 minutes to an hour, but you'd only have to do it once.
As an alternative, you could kitbash a few Poser-specific store items, then lash-up a main hallway of sorts.
