For me no. Assuming I could create compiled stand-alone file with it, in particular I run out of steam when contemplating how they would interact with the System & Finder. Also, is there an application here, or does it simply get called by the standard Finder and System disk drive routines? Perhaps someone with more experience with this sort of thing will be so kind as to help implement it.
What I did discover is that the NCR 5380 SCSI chip he uses is identical to the one included in the Mac Plus. Also, the XEBEC driver interface he uses seems to use the basic and most common SASI, legacy SCSI-1 standards.
Perhaps I am jumping the gun, but this hardware should act identically to the Mac Plus SCSI interface, possibly down to the SCSI driver in the Plus ROM. However, I doubt it will allow a 512K to boot from a SCSI device. But once the hardware is in place, shouldn't I be able to use something like the ZIP 4.2 driver to access a ZIP on the bus?
