Creating splines from the surface of existing 2d colliders

[Monomirror]

I work with a lot of complex 2d polygon and edge colliders. These already exist in my scenes. Is it possible to auto generate splines that follow the outlines of these colliders? Essentially the reverse of creating colliders from existing splines. If this isn't possible out of the box, is there a good way for me to accomplish this with the API? (I do not own the asset at this point.)
