Silver lining of the Hughes injury is Benn and Tanev have played pretty lights out together, +8 and +7 respectively and playing great defensively.
As for the PP question, I'd try Stecher, might not have a bomb of a shot but he can walk the line the closest resemblance to Hughes out of all our defense so he probably has the best chance to set up Boes and Petey. Gets his ice time up a bit too.
