Well, I guess the way to do it is to test each airfoil at a range of AoA, and select the best for that airfoil.

I would certainly remove the max camber constraint. Remember, the purpose is simply to achieve the maximum lift, at the expense of everything else. Although I think there should be a fixed chord and Re (my personal preference being 20cm and 35000, but could be anything).
