I follow your reasoning robriley.
Schioning offers kits. They are comparatively despite the use of flat panels very complex to build compared to what an HP could offer.
To hook onto the gestalt of tris one could as well build a ww hull fusing two front halves of a regular tri central hull butt to butt with an entrance to the side. For the same boat length the interior space is 30% longer in the HP. The superiority of the longer lw hull is the obvious.
How hard would it be to reconfigure the sheets and so to allow tacking for round the can races ?
