Sorry no there aren't any tools for surface simplification like that in MoI. The Sub-d converter assumes that you will have formed the sub-d control cage how you need it. If you want a simpler result you need to have a simpler control cage.

If you just kind of randomly delete rows of NURBS surface control points it would likely introduce various kinds of lumps and shape mutations. It would change the shape.
