Moving some AmEx points to Flying Blue for a trip to Seychelles and Mauritius this winter. Before we move the miles, we're plotting everything out and are trying to make sure this will work. Never having used AF before, thought I would run this by the experts.

We'd like to do two nights in Paris, three in Maurtitius and three in Seychelles, then fly back to Chicago. Does the below routing work with both a stopover and an open jaw (assuming MRU and SEZ are the same region):
ORD-JFK-CDG(stopover two nights)-MRU-(open jaw)-SEZ-CDG-JFK-ORD

Thanks in advance for any advice.
