The problem with this is at best you could have hoped for an XB1 Nintendo console with a limited library because Nintendo would be pretty stupid to leave their mobile business for a Wii U successor, there would be a high probability of the same: fewer games because they spent their
limited resources on two completely different platforms.
With Switch they at least offer their fans a relatively high quality portable experience and a chance to enjoy those critically acclaimed Wii U exclusives, and console owners a new different platform they can take anywere, even if its a modest increase in the graphical capabilities from their (still good looking and at 60fps) previous titles.
And besides that, if you are even not interested in Nintendo games you would probably wont buy a Nintendo console instead of the other ones anyways
