Unfortunately it just does not work out like that. There is too much variation in shape as you move around a face. When you try to incorporate a localized feature like the nose, the effect of the shape change will tend to stretch out along the row and column structure of the NURBS surface.
NURBS surfaces work best when they form broader curved sheets without any small scale "high frequency" bumps or lumps within an individual surface.
When you use the Network command for something like that it's trying to make one single surface that has too much going on within it.
I strongly recommend not trying to use MoI for that work. It's theoretically possible - people did use NURBS modeling for that back a long time ago before sub-d modeling was widely available but it requires an extreme amount of practice and labor and it's ultimately just not a good fit.
