I have seen a lot of interesting personal unions with the Netherlands on this site, including the famous Anglo-Dutch union, German-Dutch personal union and even a Japanese-Dutch personal union in the map thread (which may be the coolest one so far), but I can't remember ever seeing a personal union between France and the Netherlands. Because of that I present to you this challenge.
Some arbitrary rules:
The POD must be after 1543
The Netherlands and France must be equal partners, or at least as equal as the English/Scottish personal union
The Netherlands must exist at least out of current day Netherlands (with the possible exception of the province of Limburg), so no French rhineborder
The Netherlands can be larger if you wish it to be, so Flanders or even Wallonia can be part of it
So anyone interested in it?
