I would talk to a good prop shop and ask them to prove (with examples or theory as in Dave Gerr's prop book) why and how the efficiency would be improved.

It isn't obvious to me that for the same speed, running a prop slower with more pitch results in better prop efficiency. You do pick up a bit of engine efficiency, but not enough to matter.
