Could Franca-Media (Central Francia) have evolved in a national state?

For the challange you need to accomplish these requirements.
- POD after 843 AD and before 1500 AD (time enough i guess)
- No unified super monarchy like Austria Hungaria but a unified national state
- A strong national feeling (like French or Americans, may be weaker)
- The following areas must be part of it (or at least the biggest part of it)
-The Netherlands
-Belgium
-Luxembourg
-North Rhine Westphalia
-Rhineland Palapinate
-Saarland
-Lorraine
-Alsace
Bonus if:
- Its ruled by the bishop (theocracie)
- Its not technichly part of the HRE in any way
- The people speak a mixed language of Dutch German and French with Dominant Dutch (or other variation) or either French so German schouldnt be the Dominant Language
-It survives until at least 1850 (no satalite state or Protectorate)
Good luck and have fun!
Also please react i have a small idea how it could work but i really want to know your opinion.
