So after using 

g_type_add_interface_static(
    derivedtreestore_type,
    derivedtreemodel_type,
    &iface_info
);

I should be able to get the original TreeModelIFace by doing this?: 

GtkTreeModelIFace* iface = g_type_interface_peek_parent(
  g_type_interface_peek(G_OBJECT_GET_CLASS(derivedtreestore_instance),
                       derivedtreemodel_type
  ) 
)


If so, then I think I have the framework done.
