No chance this going to happen but what I would love to see is dual OS.
When you start it up you get a option to either boot to Nintendo OS which would be focus around playing Nintendo games and other social things related directly to Nintendo games.
The secound option would be to boot to Nvidia shield OS (android varient). In tablet mode it would bascially be the os you see with the shield tablet and in console mode it would bascially be what you get with the Shield android TV.
It using a nvidia Tegra SOC so if Nintendo and Nvidia was willing to go into this kind of partnership am pretty sure it would be fairly easy for nvidia to get there OS working on the switch.
My guess is it will be an nintendo proprietary OS.
