Yes, by running oz on the coco from the minicom screen, and then feeding sz 
from the minicom sesson.

correct?

Yes, 'ded filename.dsk'.  The first sector ded reads is os9's Logical 
Sector Number 0, aka lsn0, just as if you had issued a 'ded /dx@' to look 
at the raw disk.  The first 3 bytes are DD.TOT, which for that size of 
image should have been $000b40, not the $008000 I found there.  So e for 
edit, and change those 1st 3 bytes to 000B40, hit enter to exit the edit 
mode, then a 'w' and a confirming 'y'.  Done, q, y, and you are back to the 
shell prompt.

All you need is a copy of ded, the latest version from the cvs on 
sourceforge.
