I immediately thought of a couple names after finishing your list (Kurosawa, Bergman, Peckinpah, and Eisenstein to name a few), but the only way I could justify taking anyone you have on the list off would be in the interest of having some diversity in region or time period. I think 10 just might be way too short a list in this case.
I would have liked to have seen Kurosawa and Howard Hawkes on the list but that's me.
