The reason to use the PRS (precision rifle stock) is mainly because it has a flat bottom, which allows you to rest the stock properly on a shooting bag. So, while I very much like the look and features of your new stock I'm afraid that you've missed the boat on one of the most important aspects of what makes a precision butt stock. Of course, it could be very easily fixed with just a minor redesign.
I suggest you look at some of the skeleton designs from other makers of precision stocks, Dolphin for example, to see what the current state of the art is. They all have a flat (horizontal) bottom available.
I will also be one of the first customers for this stock if you see fit to make it usable on a shooting bag.
