I can think of a couple ways this would be easily possible --

Easiest - A,B,C use a database backend and all monitor host D normally
but without notification. Whichever is your notification machine has an
additional service check for the device that queries each database for
current status and sets its status appropriately. You would need to
write this plugin but it should be very straightforward.

Less Easy - Have A, B and C send their check results to a central host
then use check_cluster2 to notify based on your criteria.
