darkside suggested that being able to express asteroid orbital elements relative to a plane other than KSP's native coordinate system might improve compatibility with RSS.

This would require a way to transform inclination and longitude of ascending node from the skewed coordinate system to KSP's native coordinates. Argument of periapsis and mean anomaly are invariant under the coordinate change, but longitude of periapsis and mean longitude would need to be converted into standard orbital elements while in the skewed frame.
