It's quite a romantic idea and somehow I like it, but it will not happen and should not happen. There is one language that is understood/used much more in Europe than any others and that language is English, it's also the one language that is understood in most if not all civilised corners of the planet. The cognitive and all other efforts implied to change this would be just too big. European nations hold dear to their languages, some more than others, but slowly and surely this grasp will weaken: your films are in English, your internet is in English, your smartphone defaults to English, your code comments are in English and so on. For those who love Latin, English is not such a bad language to use; its lexicon is ~30% based on Latin.
