Remove faces of lofted breps

Hello, I would like to know if there is any way to remove faces, that are closest to an attractor, from breps created with loft.
I have attached the script i’ve used and a pdf with the 3d outcome.
Also does anyone know how i can create a surface for none planar curves like the ones produced by scaling and moving the voronoi cells?
Thank you
