Exchanging Proxy Scenes between Rhino and SketchUp

I am building a large city scene in SketchUp using Proxy Scenes. I typically make a proxy scene of an individual SketchUp model, then import it into the main scene with all the other building proxies. Can I make a Proxy Scene of a building in Rhino and bring that “rhino” proxy scene into my SketchUp model?

Make sense?

Thanks in advance!
