You can not just convert from an arbitrary SPI port to an arbitrary IIC
port.  IIC has out of band information, like addresses and message
start/end, and transfers in one direction at a time.  The best choice (if
you really want to do this at all, seems like this may be the wrong place
to solve the problem) would be a micro that has both SPI and IIC and you
write code that translates between them according to your particular
application.
