Looking through the schematics for a SASI -> ST506 controller, it looks
like all it's missing is parity.

You can still do this with SCSI. See the latest issue of The Computer
Journal, which contains a SCSI adapter for Z80s consisting of an Intel
8255 and a few OR gates.

You could build a fairly simple SCSI or SASI interface that would plug
into the WD1002-05 port on a Kaypro, but you'd have to write all the
software yourself.
