Any ideas are very much appreciated …

You might have better luck with this RhinoCommon method:

Geometry optimization related to an library

While it will result in arcs with different radii (which are still simple to fabricate), you might also consider using Curve.ToArcsAndLines: [2019-07-24%2011_01_16-Rhinoceros%206%20Commercial%20-%20%5BPerspective%5D] 190724_CurveToArcsAndLines_GHPython_00.gh (14.0 KB)

Edit: It appears to work quite well with your original curves:
