If by SCSI identifiers you mean the Linux SCSI core's h:c:i:l, then
remember that these are scsi-core internal artifacts without any meaning
to lower and upper layers whatsoever, including userspace.  (Exception:
 The c:i:l part has some significance with SCSI Parallel Interface
attached hardware.)

Stock udev already provides mapping according to actually useful
identifiers (if the respective transport provides them: persistent and
unique identifiers of targets and logical units).
