I actually agree with rather then making the Gallo provinces French, to make them Norman, infact Gallo, as does Norman, both borrow a number of Frankish and Scandinavian Germanic words from old French and Norman. but I have to disagree with the Gallo provinces becoming French in the two later scenarios. There was no great assimiliation of Gallo into French, there was no real political bond with Oil French either as Gallo was spoken freely in the courts and in the cities of Nantes and Rennes without outside influence from France. Gallo only became decimated by the adoption of French when the Treaty of Union of Brittany and France was signed in in 1532 AD. Brittany lost its independence and became a province of the Kingdom of France. Seven years later, in 1539, the Villers-Cotterêts Decree imposed French as the only official language in France. Gallo was replaced by French as the language of record and the courts, leading progressively to a situation of diglossia where French became language of the dominant minority and Gallo and Breton remained the unofficial languages of the majority.
