Latin in the EU

When/if the European Union becomes a federal state (and it is going in that direction), there needs to be one official language, which is to be the state language and that for inter-ethnic communication.

Latin, being the official language of the Catholic church and the long-deceased Roman empire sounds like the ideal choice, since it's not the language of a nation currently existing (unlike English).

Latin is the foundation for many European languages (Italian, Spanish, French, Romanian). Its vocabulary should not be difficult to learn for any European. Its spelling, pronunciation and grammar are all easy as well.

What do you think?

We could create a new language with grammar based on logic and which uses the simplest most straight forward to pronounce and clear sounds which are audible in a wide range of situations, possibly even something that can be emulated easily with hand signals or morse code.
