Katana forks, with 19" stock spoke wheels?

I've got a 76 xs650 where PO put on 2002~ish Katana GSX600F complete front end. I want to change the front wheel back to the 19" wires and still use the dual disc from the Katana. Has anyone done this or point me in the right direction? What axle to use, bearings, spacers, rotors, etc.

Ok, I've given up on the idea of putting on a 19" wheel. I'm just going to put on a 16" rear wheel from an XS400 and leave the 17" Katana front wheel on. That way the bike doesn't have a weird look to it.
