This sounds reasonable to me.  So the common denominator is to load a 
"target netlist" into gschem and show the differences between the current 
state and the target state, either by highlighting them in the schematic 
or by showing a diff?  This shouldn't be too difficult to implement.

A clever diff algorithm would have to compare connectivities independently 
of net names, so the remaining net name changes could easily be ignored.
