How to use an Esplora as a real Wii controller?

I don't even know if this is possible, but is there a way to use an Esplora as a real Wii controller? I am not talking about using it on a computer emulator, because I do not use those. I am talking about using it on the real Wii. I know there are in fact USB 2.0 ports on the back of the Wii, so that's a start. Has anyone done something like this before?
