Back to my two board configuration. The only issue in "Dual KB" mode would be if I needed a synth+synth layer on the top tier (NS3 Compact). Assuming the Song List is similar to the NE5 Set List, I'll have five quick access program buttons available for when I need to switch between strings, horns, synth within a single song.
As anotherscott said or, as long as you stay in the limits of NS scetions and if you have a good master on which you can program (and recall from NS) different zones/MIDI setups, you may also not use the Dual KBbut rather assign dedicated MIDI Ch to individual Sections or Slots and "drive" them from the master on a per-program basis.
In your example, you may activate both slots on the NS3 and then assign a dedicated Midi CH (say 5) to the Piano A section, put it in "MIDI only" mode and have the Ext that recalls a Program of the master (PX5 or other) with a zone transmitting on CH5.
