Why would you do this though? There is no need to make those curves have the same number of control points in them.

For matching segments of a one curve to another it is the number of segments that matters, not the number of control points.

Each segment in the cross piece will be matched to a fragment of the circle, this will happen no matter how many control points are in the circle or in the pieces of the cross.

If you want to control how a piece of the cross matches with the circle, then you need to use the Trim command to split the circle up into 16 pieces to match the 16 segments of the cross - to do this you would use the Trim command, not anything to do with control points.
