I can't say I fully follow what you want to do. Do you mean something like...
this?
If that's not the kind of thing you're thinking of, maybe something along the lines of converting the GFF to XML and then parsing the XML into whatever you had in mind- maybe using the appropriate portraits as quick and dirty 2D image placeholders.
Or, if you're talking about the actual 3D scene, you could try dumping an area from the toolset using an OpenGL scene dumper. I've done the reverse, dumping an entire scene from the G.E.C.K. editor and turning it into an enormous tilegroup. I have little experiences with OpenGL dumpers though.
