Lofted surface
Lofted surface from Tween curve arc
Brep grayscale
Tri-Remesh construction and smoothing
Divide lines to form points.
Randomly move these points in the X,Y plane.
Form segmented lines, derive Tween curve.
Make an arc out of the Tween curve by raising the middle point and using the end points.
Loft the segmented lines with this arc to form a surface.
