A couple more for the premium cabins is not that many.
767-300 in all Y: 290 seats, 4 exit doors (plus overwing exits), so in theory only 4 CC needed if you count one per door.
I've noticed ANA do have FA's positioned at the overwing exits, but UA don't on theirs (the ANA planes are a touch denser though, i.e. have less business seating and more Y, so maybe that changes the requirements for door staffing).
