Using Host Integrity to clean up network

Is there a way to use Host Integrity policy on a SEPM 12.1 RU5 or above to check the network for machines that are still running SEP 11 clients and cause a popup to ask them to contact thier local deskside team to be manually upgraded. Or can anyone oelse think of a way to get this to come up on machines with SEP 11 clients on them only? 

I just want to cause a notification I don't want to disable their machines or anything.
