I recall doing something similar in ages past.  I had an Osborne 01 
running CPM 2.2 and I essentially did a track by track read (like the 
included COPY program)and fed the binary to XMODEM (I had the source 
code for that) that was then received by my PC running Procomm.  Didn't 
need to bother with hex as an intermediate step.

I still have the Osborne, but now it has a Gotek flash drive in place of 
drive B. And of course a recapped power supply.
