Truncations are do-able. Or one could add a strap-on cone, while [re-]considering the fineness ratio.

The larger question is the effect of creases in the surface. A 3v sphere has a break angle of 360/20 or 18°. A prolated sphere will be sharper at the ends and smoother in the middle, with the limit case being a compound curve. I want to see if there's any 'dimple' effect with the lower frequency. A 2v would be about as angular as the F-117.
I've been struggling with an English translation of Kamm's research and what I can say is, 'don't do 'rounded' truncations.Make the cut as if you'd do it with a bread knife.Straight chop.
