For a brief (I hope) historical diversion here, the CRDS boxes I used to
use a long time ago had controllers that would support two MFM disks, a
floppy drive, and a tape on one SCSI ID.  For more recent interest, I
*believe* there exist SCSI adapters that allow several LUN0 SCSI disks to
share a SCSI address; the controller accepts the commands, chooses a disk
by supplied LUN, and returns the results.
