So...my guess is you can take the stock blades and re-attach them to a new center-bore at whatever pitch you want?????? Or am I completely missing something

Very slick Terry!  So are you going to make a 22xx, a 23XX, a 24XX or 25XX version of a 2170?

That solution was responsible for the sudden increase in the G1 SAW speeds.  The engines are rpm limited so more pitch is the only answer.  You don't need to get quite that fancy if you have a prop duplicator of the stock or cupped prop.   Cut most of the blade from the leading edge, and bend each blade up the same amount from the mold.  Then carefully rebraze the blade to the hub.  Heat treating the prop afterward is a good idea as well.
