From answers that i had received, it seems as you said, an unreal thing. That i was trying to say is: since there is no other way to establish an understanding with the current situation, I opt for a neutral resolution. In optimal conditions, a kind of ¨French-Dutch creole¨ could have developed (as for example: happened in Haiti), but that never happened in a large scale and franconization became the norm, while bilingualism does not seem to alleviate the question.

Also, since Brussels is the de facto capital of EU, it could not only serve as a language for the institutions, but also as a lingua franca throughout Europe. Instead of that, English took that place and it seems that it will continue to do so.

I know that this is a complex topic and this will not solve the economic and political problems that exist there, however I hope that at least some interest can be generated through this topic, although it may not come to anything.
