Wow! what an awesome idea.. The future is here finally boys... Next i want real Hoverboard Mr. Meyerhoffer. Like from Back to Future 2. Get to work!
Maybe there's a niche for it, maybe not. I'm just not sure that a considerable number of surfers exist that would prefer a 3-piece prefab surfboard when they can pay the same amount of $$$ for a 3-board quiver that would be fined tuned for a variety of conditions. Maybe a poor analogy, but I personally wouldn't want to fuse a Les Paul neck onto a Stratocaster body. But I will admit that it's a unique and unusual concept.
Shape shifter is a cool company. I saw a Taylor Knox board at the surfboard broker sale last year. Really interesting concept, if you want to switch up the tail https://www.surfertoday.com/surfing/10384-shapeshifter-promises-a-surfboard-tail-revolution
Dudes do the same thing, but with a CADD file. So in terms of "shaping," it's already been done. I see the advantage in travel; the disadvantage in weight and flex.
