I was thinking G41 or G42 with a cutter with a diameter of say .05 at the
point and a diameter value in the control of .06 and that would give you a
.02 trace width. No editing required but it does require a control like the
ahha that accepts tool size input. Then with a change of tool you could
drill the holes.
