I'd like for the EU to transform more into a state, but that will be hard unless the local powerful are willing to give up their power. The concessions that had to be made to get as far as the EU is today are also part of what is holding it back. Thankfully a significant veto power will remove itself from the EU in the coming months.
A huge reorganization such as setting up a proper new state seems easier with help of some disruptive event like e.g. a war or imminent war, something I hope the EU won't have any opportunity to take advantage of.
