How could Nintendo implement a Switch Pro?

Pyro as Bill said:

Dock: $89
Dock+: $149. TX1 (overclocked/no underclock) in a dock for better home console performance (stealth dedicated home console).
Dock++: $229. TX2 (overclocked/no underclock) in a dock for much better home console performance. 2nd home console.

Tablet: ~$130-$150 (after ~$50 price cut)
Tablet+:~$200. TX2 tablet with same form factor, better battery life, improved docked performance (or same form factor, same battery life, improved undocked and docked performance)

So a Tegra X1 or X2 in the tablet and an additional Tegra X1 or X2 in the dock?

How would both SoCs sync the data? Over the same USB-C port which already handles the HDMI stream and the network stream?

Would the SoCs sync with Tegra X1 performance even if one of them is a Tegra X2? Or would both run with max performance?

Would the SoC-dock come with its own memory or would it share the tablet memory with the other SoC?

If the SoC dock has its own memory: What happens if you undock the Switch?
