In that setup, it would be like having a compact Wii U with a gamepad attached to it on the "go" and at home it would be detached with console part in docking and screen/controller (or gamepad) in user' hands. That would mean that the pluggable main body would be the NX itself and all the rest add-ons.
In that setup, there wouldn't be detachable controllers but the main unit would be the one that would be removable, leaving you with the controls and a screen that wouldn't work, as the hardware to make it work would be docked to the TV.
I don't see this setup working.
