You mean something like this?

I did it by moving the points away from the circle instead of culling
them. Then connect all the points to an interpolate curve component
and extract the desired sub-curves. I decided to move them gradually,
but you could move them so they are all completely outside the
circle.  They look weird because of the low number of points. I used
only one of your circles in this example.
