Loft curves&points question

Hi everyone,

I know that The standard  loft component within GH will not loft curves and point .Today ,I intersect a series of pipes and the same numbers of spheres to get couples of curves ,and then loft them to  conic surfaces (like hyperbola etc) .However,there always a hole at the center. At first, I controled releated params carefully so that the hole bacame enough small. But now I find this is not a good enough way for the hole may become bigger with some tiny modification .I guess one solution can be a script loft component??but I cant reach it with my poor knowledge about script . So here, I ask you talent guys to help me out !Thanks in anvance.
