I just think it's an extremely strange choice to go with a land based off of Paris, which is only in one single movie which was also the least successful entry in the whole franchise, when you could easily do a land that incorporates a huge key aspect of both HP and FB. The general guest will find either stunning, but do you really want to let down the Potter fanbase? The group that's actually interested in spending a wild amount of money on merch, food, etc?
I get your desire of moving to a different country just to freshen it up. I just don't see it making logical sense from a marketing or financial standpoint.
