The flip of the cities in Northern France represents the Norman invasion of England. Basically England becomes the Norman Kingdom.
Calais is not a part of Normandie. Caen makes sense to flip over, Calais does not. I understand what the present flip is supposed to represent, but it in the case of Calais, it doesn't makes sense. It did not become officially English-controlled until 1360, under the Treaty of Bretigny (before that, it had been besieged in 1346). The Norman invasion of England started in 1066, about three centuries earlier. William the Conqueror's forces mustered well south of Calais before shipping out. Much of the remaining gains of "England" took place a century after the famous invasion, during the mid-12th century, as a result of Henry Plantagenet's marriage to Alienor of Aquitaine (and his inheriting Anjou, Normandie, and the throne of England).
By the way, Normandie never was a kingdom. IIRC, technically it was vassal duchy of the King of France. Brittany should really be in place as a neutral early in the game. It was a duchy that flipped back and forth between France and England, before becoming permanently a part of France in the 1500's. But I'm sure you know all this. Naturally, that kind of a change will result in modifying in some way the UHV's for both France and England.
Political marriages were considered in the mod early on, but at this point it is too much work to implement and balance.
Of course... It was just a pie-in-the-sky idea.
