I think in the EU context, the real issue is: can the majority of us consciously adopt multiple identities? Because a not insignificant part of humans always do and did, in many European countries this is already a defining thing (Bavarian/German, Catalonian/SPanish, Scottish/British, Algerian/Marsellaise/immigrant/French/European, etc.) - so the question is, can European-ness become a meta-identity for most EU citizens.
