Most SCA drives I've seen have also had jumpers to set the SCSI id.  It's 
possible that you could use a cable like this one, and set the ID on the 
drive, overriding (or combining somehow with) the ID set by the 
backplane.  More of an issue, however, is figureing out how to mount the 
drives, and being careful to not overload the cable since the power for 
the drive runs over it as well.
