Unfortunately, it's too late for that - they made it essential part of the design and centered all their effort around it. But yes, in my opinion, it would've been much better if they went with better hardware instead (7750 level GPU, quad core AMD CPU), and Wiimote 2 + Pro controller instead of Gamepad - that way they would build on what made Wii so popular, plus provide 3rd parties with hardware platform that would be very easy to port to.
