A 706 should have similar dimensions to an M or could be modified to it. Find what they called a super snoot. Used for picking ear corn with a mounted picker. Lots more surface in all directions for any wind to help you out.
Otherwise a rotating screen off old combine would be harder to fab together but more effective.
