I understand perfectly what you're trying to do, and applaud and commend you for your curiosity.
This thread will have dramatically increased your knowledge of issues related to the EPL, but I don't believe it has answered your original question anywhere near authoritatively enough to warrant your usage of it in the given scenario.
Given that the readily available documentation on the aircraft (and engine) does not address this question, you would need to obtain positive, documentary evidence from both Cessna and PWC before committing your mind to that course of action. I would not automatically believe what any LAME has to say on the matter.
In the absence of such confirmation, I would just use the power lever, but without concern for exceeding torque, temperature or Ng.
Good luck with your flying in PNG!
