In my opinion, this is a terrible idea. First, because most of our evidences, archaeologically and historically, are related to the Odrysians. Second, because this is incoherent, we don't do the same for other cultures. Else, why not dividing Getae and Dacians? The same for Illyrians with the Autariatae, Dalmatiae, Dardani, Ardiaei etc.
