The ends just wouldn't justify the means by taking all that out. No thanks.
I would prefer (being we're in the third year of its release) keep everything, keep pumping out AMAZING quality 1st party titles, keep funding some diverse third party titles exclusive to Wii U, Hand over some IPs to third party devs to experiment for "favors" down the line (will also be funded), get the third party support that comes, learn a few things this gen (not just on the development side, but architecture wise, and learn what the fans want) and implement them next gen.
I personally think if they change the Wii U in any way besides a redesign with more memory, it will make the console flatline like the Vita. 3DS has been out for 5 years, which is why people are okay with upgrading, Wii U has been out 2. People are currently looking and people are interested. It's going to be 3rd out of the 3 consoles and that's just something Nintendo has to face. I think when they see their bank accounts swell from the big 1st party title releases though they will sleep well enough. Profits seem to do that for some reason.
As for removing TVii, why? Whatever negligable boost it gives in performance 3rd parties will never use anyways, and Nintendo doesn't seem to need it for their 1st party titles. I don't see 3rd party titles that aren't already coming to the Wii U all the sudden hop on board because they have a tiiiiiiiiiiiiiiiiiny bit more power.
