You could, at least leveraging the host system config properties that vR Ops collects. You could create new alerts+symptoms for vSphere 6, or update the OOTB alerts. I'd personally do the former and create new alerts+symptoms and create a new group to apply that new policy to only v6 hosts, that way you've still got v5.5 and v6 harden in place reporting on the appropriate host versions (mixed v5.5 and v6 for awhile likely).
If you find this or any other answer useful please mark the answer as correct or helpful.
