The short answer is no, because the Wii U's problems (in 2013) extended beyond the product's price. There was a similar thread from Chubigans that discussed the viability of a GamePad-less Wii U -- there were some very interesting arguments in that thread from both sides of the fence.
It's critical to note that the Wii U's failure really wasn't due to it's price-point. I kind of dislike using the four marketing P's because marketing is significantly more complicated than four concepts, however, I'll use them here to give a brief explanation of why the console failed.
Product - The Wii U's technical capabilities are poor, and in comparison to the PS3 and Xbox 360, the value proposition was way off. Nintendo were asking people to go out and spend hundreds of dollars for a product that didn't offer a significant leap over current products. The Wii U's GamePad was also a technically limited product. It could not match or exceed what tablets were doing at the time, thus the value of owning one was very low. For developers, making games for the Wii U wasn't exciting due to the limitations and outdated technology in the product. For publishers, adding a Wii U SKU was an investment not worth taking, as a) The product wasn't doing anything technically compelling that could create a 'wow' factor for a game and b) The non-existent marketshare guaranteed a financial loss. The Wii U is a poorly designed product, and this is ultimately the biggest reason why the console failed.
Price - The Wii U was priced at $299.99 and $349.99. The Wii U launched as a technically weak product with a low-value feature along with an extremely small game library, and it was being priced higher than the immediate competitors (360 at $199.99, PS3 at $249.99). If you were a parent looking at what console to buy for your child, the Wii U wasn't an appealing product. There goes the casual gaming audience.
Promotion - The Wii U launch ads were horrific. The messaging was so confusing that you had and still have people who think the Wii U is a new controller for the original Wii. 90%+ of the press shots featured the controller in front of the console, 90%+ of the ads focused on the controller and not the console, 90%+ of the ads also showed the Wiimote, 90%+ of the store displays had the Gamepad as the hero and not the console, 90%+ of the media tours (e.g. Jimmy Fallon appearance) featured a Nintendo representative talking about the controller and not the console, the list goes on. I feel confident in saying the promotion of the Wii U did as much damage as the actual design of the console. Remember the brilliance of the "Wii would like to play" ads? None of that was present with the Wii U. I've said this before, but if Nintendo doesn't realize how bad their Wii U promotion was, then the NX is going to meet the same fate. I guarantee it.
Place - The Wii U was an HD console launching 7 years after HD consoles had become 'a thing'. In hindsight, Michael Pachter was 100% correct in saying that a Wii HD should have launched years before the Wii U. The Wii U also launched months before the shiny new PS4 and Xbox One were unveiled. It absolutely had a head start, but that head start was short lived due to the public realizing how technically weak the Wii U was in comparison to the PS4. Nintendo couldn't rely on "Most powerful console" as a selling point, so Nintendo had no chance with hardcore gamers -- who also happen to be the early adopters of any console.
For the people who still believe that price (due to the GamePad cost) was the Wii U's Achilles heel, ask yourself the following. How many people who could buy the original Wii at $249.99 can't afford a Wii U at $299.99? Furthermore, given the sales figures of the PS4 -- a $399.99 product -- isn't the 'it was the price that killed it' argument essentially baseless? Let's take it a step further. Given that the Gamecube failed to sell well even after a price cut to $99.99, would Nintendo want to invest millions of dollars into figuring out another control scheme (i.e. So as to reduce the console's price) only to not make those millions back?
