I've not heard of "scaling" polars that way so I don't know if it works. Perhaps an e-mail to Bob Perry would be fruitful.
Your diagram above has the targets in it: The little boats that are labeled "optimum tack" and "optimum gybe." It's tedious to count hash marks but the data points are in there.
ORR has data for the Moore 24 (from their proprietary VPP). US Sailing also offers a "performance pack" that will give you pages of this stuff - for a price.
