Depends on what you mean by tried and tested.

I told you to use Ersatz-11 and buld the image directly
on the SCSI drive.  Ersatz-11 works fine under FreeDOS.
Disks are cheap so you just make a different disk for
your system.  I have used this method to make RT-11, RSTS/E
and BSD-211 systems disks that successfully boot and run
on my 11/93 with the CQD-220A/TM controller.

You could probably boot your image under Ersatz-11 and then
copy it to the SCSI but the  method above works just as well.
