We've got something very similar to this in the kernel already and it's
called iSCSI. iSCSI is a moderately straightforward encapsulation of the
SCSI protocol in TCP. It's not great, but at least it's standardized.

If you have code that generates SCSI packets in userspace, it's
relatively straightforward to convert those to iSCSI packets and serve
them over TCP and then attach to your virtual SCSI device from the
kernel. And yes, this even works with things other than disks.
