I think it could be done with a bit of coding. Most of the involvement of motion controls in the game were just a gimmicky "ooh, look if you swing your remote this way, the sword goes that way too!" it didn't have to be in the game. A simple bit of coding to have Link use the appropriate slash for the situation based on which direction you point one of the sticks/circle pads would accomplish exactly the same thing as motion controls. That's all motion controls are, they deal with rotation. The information that the game uses for those slashes are two things: one, sensing that it's being moved, and two, a pair of numbers that represent its orientation in degrees on two planes, giving a three dimensional orientation. For the first, you just need sword button. For the numbers, well you don't need two directions in that case because the other can be automatic based on what is necessary for the first, or can be done with the second stick. It'd be the same directional slashing that was in OoT, MM, TWW, and TP.
I know go technical, but the bottom line is, yes, it's absolutely possible since all motion controls are, are button mapping of traditional controls. So it is simple to reverse it.
