I'll take your word for it. But:-
Do you imagine a Europe-wide reconfiguration is
a. possible or
b. meaningful for anything but a fleeting moment of hope?
Isn't there any danger we might become like Tariq Ali dedicating his 1988 work, on the possibilities that Soviet glasnost/disengagement from Cold War militarism offered the British left, to purged political hero Boris Yeltsin?
Seeking to make hay out of opportunities that present themselves by chance, not of independent working-class-dominated pressure, and then ending up with egg on your face?
I see all the discussion of EU/non-EU as essentially two ways of reaching the same goal making capitalism in European areas profitable with respect to (re)emerging competitors like China, Brazil, Russia, India, South Africa.
