If you're really just looking to only use this to play Tatsu vs Capcom, your best bet is to either find a PS2 stick and use a PS2 to GC converter (Red Octanes are pretty good if you can find one and it has PC and Xbox support) or buying a Hori stick for the Wii.
Your other option is to see how the Joystick is structured and see if you can wire a new PCB board to the buttons... but if that's if you're really dead set on using that specific controller for the Wii.
