Converting Curves to Arcs - Rounding to Whole Numbers

Hi all,

I am trying to convert curves to arcs, but with a slight caveat: I want the arcs to be rounded to nicer numbers.
Is there a way to tweak the command to achieve this? I don’t mind having slight deviations from the original arc, since those arcs have already slight deviations from my original NURBS curve anyway, as long as they don’t look horrible it would be totally acceptable.
If rhino could compute this convert, they would all be in tangent with each other, which is also paramount to construction. Doing this manually would be devastating.
