I don't think you'd need to do that at all, any more than you'd have to reconfigure your mouse for a smaller or larger monitor. If you think about moving a mouse, the amount you move the mouse isn't the same distance covered on screen by the pointer, but the distance from one side of the screen to the other is the same on the mousemat no matter how big the screen (although you can change the sensitivity, but that's not related to screen size). The Wiimore is similar in my opinion. You move right a little, the cursor moves right. As long as you can see the effect, it doesn't need to relate exactly.
