If I was in SK's shoes, I'd make similar changes Joshua.
Our right side leaked, so we need to plug it with some smart defence. If Ben Smith was available, he'd go straight to centre. Horo is available, so why not try him in Morgan's place, and shift Morgan out to the wing (and let Blair learn a little more in lower grades)? That's assuming Hayne is still out - if so, Burt was itching to contribute more and be fullback, which would free Sio up to return and contribute strongly from the wing.
Surely SK needs to rotate Keating and Maguire at dummy half every 20mins, and keep things fresh.... If Keating can play longer, then leave him out there in the final 20 as a tackling extra lock or something? Just keep the dummy half/service area fresh and fast please coach!
Something was going wrong in defence with our edge forwards marking up properly too imo. I'm not sure what the answer is there though... SK has had Tautai and Shack as 18th men this season - probably time to give them a shot at least from the bench? (And with Shack's facebook stuff, who really cares? Just fine the guy $5K for stuffing up, and then get him on the field asap to prove what he can add to this rabble.)
