more then likely you would have to get a shorter inner tube witch would not be hard to do. Then you would need a wheel so thats $1500 and a wheel spacer break line and new master cylinder and a break caliper. Shopping ebay would be the cheaper way to go. There is a shop on ebay that sells parts off crashed bikes and they would be great if you can find them.
So you might spend $3500 to get the dual disc look you want. Is it really worth it
