Map geometry from one surface to another

I have a "tileable" geometry that I have built along a rectangular base surface, and now I want to map that geometry onto a curved target surface relative to the base surface. The example I have provided is a simplified version of what I am trying to do, but captures the problem areas. My "tileable" geometry is the same length as the base surface, but some elements are offset and overhanging. I don't want to split the overhanging geometry at the front and fill it in at the back- I need the relationship of my geometries to stay the same (list order matters). In the example, I map it to one circular surface, but it will more than likely be mapped onto a more twisted surface where the tile may be mapped onto multiple surface segments that form a loop.

I know what the problem is with my script- Srf CP is pulling the overhanging areas to its edge, which then makes it evaluate to the wrong position on the target surface. I know that we can evaluate a reparameterized surface with UV values less than 0 and greater than 1, but is there a way to find the UV value of a point that is beyond 0 and 1 of a surface? Sort of like the reverse of the Point Oriented component, but with a surface.

Maybe there is a totally different way to do this?
