As all cars are built by computers and each option scheduled for each car it is actually quite economic to fit just the parts/plugs and wiring looms you require rather than everything with the same wiring loom.
And Mitchy is correct, you need to swap both climate units and add ducting and a new wiring loom. It is not a simple job, I have looked into it on my original A7 2011 as I was disappointed with the dual climate display.
It was possible on the old C6 A6, but not on the C7
MY2014 S7, Phantom Black, 21" rims, Heads up display, Front and rear camera, TV, BOSE, Lane Assist, Side Assist, Adaptive Cruise, Traffic Sign Recognition, DVD changer, Audi LED logos, Lighting pack, MMI touch with Audi connect, lots of others I can't think of but I know they are there.
