If you can get TeleDisk files of them, send me a couple of samples 
and I'll work the 22Disk stuff out for you.  After we did 22Disk 1.x, 
we ran into a bunch of formats with bizarre formatting (dissimilar 
sector sizes, tracks distributed alternately from the middle of the 
diskette, varying sector numbering from track to track, etc.)  We 
built a 22Disk 2.0 to handle them, but it requires that the format 
definitions be compiled in, rather than as a text file.  On the other 
hand, it caches directory tracks and works out the fastest way to 
read a track (I/O is track buffered).  So there may be some hope 
there if things are really strange.
