Multi-lun is rapidly becoming obsolete: any modern devices conforming to SCSI-3 use REPORT LUNS instead of doing LUN scanning, which gets us out of the issue. Conversely, the ancient devices which rely on correctly setting this are more likely to get upset about any change in the balance. In your case, just add the changer's inquiry strings with a BLIST_FORCELUN.
