Extrude tweens to perpendicular

Hi everyone, your insights and help with this would be great. Is it possible to extrude each tween to its perpendicular direction?

Please see the gh file
tween to perpendicular_01.gh (6.7 KB)

Something like this?

I’ve put 2 options,
one were you simply extrude to the normal of a surface, with one value.
second, where you project each curve to the next plane (along the normal), and then build the brep from the two curves.
