Decomposing and recomposing star shape

I have star-shaped sections that I want to make a loft. But firstly, I want to offset spikes of odd sections than combine with existing dots to form a star-shape again. But I could not manage the data set, yet I cannot merge two list properly to draw a polyline.
Thanks in advance. (16.6 KB)

I’m not sure what you mean with offset the spikes of odd sections, maybe something like this? (12.4 KB)

You can create star with GhPython (12.9 KB)

Thank you! I wanted to fix the interior points while offsetting the outer points of the star.
I can work on that.

Thank you! I am not expert of python, but I can work on that.
