Didn't one or more of the America's Cup sail boats have something like
this in one of the last sail off's?

They have tried a textured surface (more than a couple races ago) but the
rules were changed again to outlaw this sort of thing (along with surface
tension modifiers that you drip into the water at the bow).

I don't believe that the "shape shifting" idea has been attempted in real
life - But you are right, it's not exactly a new idea.
