Why don't you folks just have one printed and test it for yourself? https://www.thingiverse.com/thing:4271780

Works great with a Walsh Bb chanter reed (may have to trim the staple slightly) or a McCallum standard A smallpipe reed. This one doesn't have the double-holed G, but otherwise is acoustically very similar to the point where I couldn't tell if it were the real chanter or the P&P version.

I enjoyed your clips on the Lindsey chanter and pipes. It retains the small pipes sound, but gives much greater range, which I assume you like.
