I can only speak for OctaneRender for Revit (and yes, I know that's not an option for you).....in that plugin you can select a Revit family instance and assign a proxy to it.  The proxy is either an OBJ (A clothed and posed Poser figure exported as OBJ works) or a pre-packaged Octane Standalone geometry element.  Then when you render in Octane from the plugin, that OBJ proxy (the Poser human figure in this case) renders in the scene in place of the family instance.  You can then scale, rotate, move and change the materials of the proxy geometry object.  This is all done from within Revit - no need to export to another modelling or rendering app.

Going from Revit to Poser is unlikely to work - because when you export from Revit the materials are lost.  A workflow that might work is going from Revit to 3ds max (since I think 3ds max can read the Revit material libraries), then export to OBJ and import into Poser.

The other thing to consider is that unbiased renderers are typically very slow at rendering interiors (since they have to process ray bounces through glass, etc) - so you want the fastest renderer possible.
