Anone tried SSBC rotors for KH swap

Has anyone tried putting a SSBC rotor on a stock KH setup to increase the bolt pattern to 4.5? Wondering if it will fit and align to the calipers?
It will not work. No one to my knowledge has a bbp conversion rotor for the KH. I have just converted mine to bbp and had to purchace all the parts for the complete conversion. I waited for years thinking someone would eventually come out with one and no one has.
Spindle and bearing sizes is the issue here.
