I was actually thinking the inverse of this earlier. The smart connector on the iPad Pro seems to be capable of many things and perhaps a lot more that we don't know about. So what if Apple was to launch a iPP dock similar to the keyboard on the Surface Book? basically a rMBP without the screen that you could dock into and use the iPP as a display. That would be kinda cool, redundant but cool.
I'm recalling a scene from Ed, Edd & Eddy, the episode
One + One = Ed. Edd, double-D, exclaims while vigorously writing notes in the midst of an ethereally morphing environment, "Hello! An original scene transition... interesting!" The start of the following scene is where I find us with Apple: completely in the dark.
Follow me here. Apple didn't like, or maybe didn't notice... hasn't consulted me regarding, at least, my suggestion to install an operating system on a
cable that links their iOS devices together. Your idea here is essentially the same, but I won't reiterate my silly nudge to nabbing the Final Fantasy naming scheme for such an "OS X 2." Hear me out, it's four simple steps that obviate a magic:
1.) dock iPad Pro or such iOS device with Smart Connector
2.) app icons, Springboard, etc. react to physicality of the docking-motion
3.) logic falls into place, Dock & Finder rise to the screen
4.) MacOS device!
Now what the heck was the use-case that made connecting an iPhone to an iPad Lightning-to-Lightning-wise seem like such a profitable endeavor... "is Eddy rich yet!?"
