I would change up out PP to the Caps system which technically does not have a guy out front.
This.
The whole 'net front presence' is going out of vogue. More and more teams are wisely leaving the goalie to peer around that guy instead of trying to move him and turn a simple screen into a moving double screen. Thus turning the PK into a functional 4-on-4 as far as coverage while the guy in front stands around holding his dick.
The Caps system, where they have one guy (Ovechkin) at the left circle, another guy in the high slot (Oshie), and a Dman with a shot at the right point (Carlson) is much more effective than having some lug stand in front of the net while the rest of the team predictably send the puck up to the points for shots in hopes it bounces the right way off somebody's ass.
It doesn't have to be that exact formation, but ideally you want three options at different ranges and a playmaker that can curve off the half-wall or behind the net to deliver the pass.
That's all moot if nobody is willing to move the puck quickly and move their feet, though. The PP cannot continue to be 'get the puck to Kane and stand around while he stands around stick-handling the puck in place while the clock runs down'. The other players on the ice have to move to give him options, and he has to move to create some options and draw coverage to create lanes.
