topology for layers that are associated with parcel fabric

I am exploring the use of parcel fabric to edit our parcels.  We currently have a topology defined for parcels with feature classes such as Zoning.  The rule associating the two is "zoning area boundary must be covered by boundary of Parcels".  We have marked about 1000 exceptions to this rule where zoning unfortunately does not follow parcel boundaries (zoning follows a natural or adminstrative boundary, or crosses a road right of way).  If we try to associate zoning with the fabric so that it can be adjusted and kept in synch, how would a zoning polygon which is only partially coincident with parcel boundaries behave when we try to automatically adjust?

If a standard feature class such as a zoning polygon is associated with the fabric - the idea is that if the fabric is adjusted to control using the fabric least-squares adjustment, the zoning polygon can receive those adjustments as well (afterwards) and remain in sync with the fabric.
When the fabric is adjusted to control, the coordinate changes are saved as vectors. The vectors are then used in a feature adjustment to adjust any associated feature classes.

So the vectors stored from the fabric least-squares adjustment are used in a rubbersheeting process to adjust overlaying feature classes (similar to the spatial adjustment functionality.)
