Can I make my SE ps3 stick work with my wii?

Is it possible to make my SE ps3 stick work with my wii as well as my PS3, by adding in a flip switch or something? I know I’d have to change my PCB out, so what would I use?

buy a multi-console cthulhu. it has support for gamecube as well as ps3.

Toodles has the new PiiWii now.
It is a Classic Controller.

Ok I looked up MC Cthulu, It looks like I’d need to cables coming out of the system, is that right? Thanks for the speedy replies

Better yet, how difficult is it to use a classic controller to mod my own stick? I will have an extra joystick/buttons as soon as my Sanwa parts come in the mail for my SE stick.
