How can I incline contours on a loft progressively?

Hi guys,
So I have a loft made a loft of 3 closed curves and I want to create contours that I can incline progressively when they reach the top. The closest they are to the top of the loft the more inclined they are.
Any help would be very appriciated :-)

Instead of contours, I used rotated planes.  There are three controls:

  1. 'MD Slider' picks a reference point and orientation for the initial plane.
  2. 'Domain' slider sets the total angle of rotation.
  3. 'Steps' slider divides the angle domain and incrementally rotates the plane.

Finally, 'Sec (Brep | Plane intersection)' returns the curves where the rotated planes intersect the surface.
