Of course megasas doesn't. Megasas is a SCSI HBA emulation, not a
SCSI device emulation.
You'd have to use two device specifications here:
-drive file=/path/to/image,if=none,id=foo -device megasas,id=raid
-device scsi-disk,drive=foo,serial=1234,bus=raid.0
or
-device scsi-disk,drive=foo,serial=1234,scsi-id=0
