> I am optimistic ... The EU has leverage. And the revanche towards UK may unite the continent.

Many don't like the 'heavy hands' of Russia, Turkey, China and then here we have a disappointing, difficult voting result and we (you) talk about revanche?

The correct answer should imho be that EU introspects about what needs to be changed that such an important country as the UK would happily vote to participate.
