Creating a Virtual set import into Motion

My question is can a 3d model of a virtual-set be created in something like Maya and imported to Motion in such a way as I can change camera angles and create a unique background for my chormakey subject in FCPX each week?

Details: I want to create a simple virtual set which is glass. This way I can change camera angles, place a different scenery video behind the glass cast shadows and light etc.. I have a guy who can build the set but im not sure what format he could use or if its even possible to create a semi-transparent object and have motion recognize and work with it. My guess is I am asking far too much of Motion. Any thoughts or directions would be great.
