Completely do-able and easy (FC3 and FC2 had this kind of "unfinished" and story-exclusive stuff in a hidden folder or separate object inventory XML file) but I don't see it being worth it right now; not until whether an confirmation about if an PvP map editor is coming or not.
I'd suggest extracting common.dat/fat (Gibbed FC3 tools work with FC4 just fine, mostly.) and seeing the ingameeditor directory.
