Brian - This sounds like a really interesting trip. The architecture is bound to be varied, as you are only repeating architects once. With the exception of Muirfield Village, Olde Stonewall and Beechtree and Saratoga Nat'l, I've played the others on your list, and I think you'll have a really fun time if you try to look at each course and how it fits in the overall group. It will be nice experiment.
If cost of play isn't too prohibitive, you might want to try Atlantic City Country Club around the time you play Galloway, and maybe Hidden Creek too, if its doable. Also, between Olde Stonewall and Saratoga, there is an interesting Ross course (Tegeuga) and an Emmett (Leatherstocking) that can be achieved either publicly, or without too much arm twisting. Lastly, you might want to try Taconic after you play Saratoga, which is just across the border into Massachusetts (in Williamstown). Beside that, I have nothing else of substance to add.
