Yes, that works.

No, the data is intact, as the mounting of the image file with
the loop option confirms.  Also, further experimentation seems
to suggest that if the floppy disk is physically mounted in the
floppy drive during boot, then I can logically mount it with the
mount command after boot.  This really is looking like a bug.
I intend to file a bug report, but I'd like to do some more
trial-and-error experimentation before I do.  Thanks to everyone
who offered suggestions.
