It is 100% possible. But how many time do you want to pay? but actually the thing to get it working is to REPROGRAM THE WHOLE GAME!! , because everything is based of wii remote. If nintendo wanted to make it with classic controller, they will easily did it. Probably it wont be released. Why? Because 1) if someone NOT FROM NINTENDO releases this, he will get a very great punishments about copyright. 2) You are the first person that want it controlling from classic controller. 3) Playing with the wiimote is fine, the whole point of the wii, is remote control and that the wii remote can act as steering wheel, bowling ball etc etc. but yeah, its absolutely possible.
