Before i go down an internet rabbit hole..... Is this even possible?

Is there a way to setup a wiimote as a controller in rcps3? The reason i ask is because of guitar controllers. I have a wii one and would like to use it in rcps3.

If Windows detects it as a controller when you plug it in (or pair it wirelessly) I don't see why it would be a problem on rpcs3.
