A separate program would be written to re-assemble the nibble images

disk that has a non-standard format that would work (assuming the
secondary protection in the nibblized images).
Just to add a bit to your archeology, IIRC, this approach was taken initially
on Wings of Fury by "Mr. Slick" (back in the day). See here:
except rather than nibble images, compression was used to "pack" and "unpack"
the data (as compression was called within the Apple II circles then). But the
result was a working 18-sector version. He also provided a copy utility that
could be further generalized for other programs. [The fixation to get
everything back to 16-sector format likely missed the opportunity to pursue
preserving use of the 18-sector format and just working around it.]
