Hello from Wisconsin,
Depending upon how you plan to get from one location to the next, this looks good. I hope you have reasons for each location mentioned so your time is allocated correctly. Taking a train or even renting a car involves time. getting to the station, getting from the station. Or, better yet finding place to park a car in medieval cities.
Several responses are suggesting expanding the Normandy stay. 2 nights is only one day. Bayeux has a fine cathedral, but then again, maybe you have no interest in cathedrals. Bayeux also has the tapestry depicting the 1066 invasion of England. Once agin it might not interest you. There are several WWII/Landing museums in the city too. Unless you are a specialist in the D-Day landings, one broad beach is pretty much like another broad beach. One gigantic cemetery filled with your countrymen is pretty much like any gigantic cemetery of people who had to cross those broad beaches facing withering rifle fire. In short, one beach, one cemetery, one German gun emplacement and you can head out. That is a big day right there.
Steven Ambrose has a pretty fantastic book on the on the landings and the days afterward. D-Day and my favorite Citizen Soldier. In advance of the trip you might read those.
