I'm undecided on this.
1. This particular design has been done before (GameCube-like with a big C-stick), e.g. see the Hori Classic Controller: http://www.hori.jp/products/wii/wii_classic_controller/ or the officially licensed controllers by PDP: http://www.slashgear.com/pdp-multicolored-smash-bros-gamecube-controllers-get-cute-11333155/. If you really want the GameCube controller layout, there have already been other options to choose from. (Albeit in a different way of "wireless" as they plug to the Wiimote, see point 2.)
2. For being called the "WaveDash" controller, I believe any serious Super Smash Bros. player would be very unlikely to go with this option. A wireless controller always adds to input lag, no matter if there's a Wiimote in between or not. This is what I believe to be the main drive for Nintendo to create a wired adapter for GameCube controllers for SSBU. Naming a product plays a big part in how a product is received. "WaveDash" just seems like a lazy way to attract the SSB crowd, even though it's far form being the optimal choice to play a game like SSB. (Rumble? Seriously?)
3. If having a wired controller is a problem, it's already established that you can use the WaveBird controller with existing "GameCube to Wiimote" adapters such as from Mayflash and in the future with Nintendo's official adapter that connects directly to the console. So you'll have an ugly looking mess with a Wiimote and two dongles hanging out of it if you get the Mayflash, but none of that should matter because all of that can be out of sight as the WaveBird only needs a stable RF connection.
4. Finally, even though the layout is nostalgic to some, having it for games it's not designed for will make for an overall bad experience. ABXY buttons are positioned very differently on the GameCube and Wii U Pro controller layouts. It may work in some Wii U games, but not necessarily well in others. That's not a bad thing, but considering a wired option enabling use of official controllers with minimum input lag is soon becoming available, I don't see the reason for this "WaveDash" to exist. Besides, who's saying the quality will be any good? I still have GameCube controllers from launch and they work beautifully despite being worn and beaten to the ground.
Just my 0,02€.
