I think that's probably likely with the way Kovacevic has emerged.
If it were me, I'd run 7 D and cycle Casey in at F and D and let him run PP2 with Hamilton.
It's also a nice option to have to be able to insert him in at either side on the backend if we are trailing late and need to create offense. Like, if we're down 2 goals heading into the third, it would be a great option to have to be able to shorten up the bench up and roll with:
Bratt - Hughes - Mercer
Casey - Hischier - Meier
Cotter - Haula - Noesen
Casey - Casey (40%)
Casey - Casey (40%)
Casey - Lovejoy (20%)
