Good luck on finding the answer.  

But have you considered just buying a used, working 80-track 5.25 FDD?  The Kryoflux is only reading the magnetic fields recorded on the media and only cares that the drive can step between tracks; it then interprets that set of numbers into data representing the disk type.  The disk can be MFM or GCR as it doesn't matter until you tell the type of disk format it read.  It doesn't care about the number of sectors as to whether it is 11 or 22, as they are just changes in the magnetic "flux."

I could be wrong now.

Correct, except that the reader software may need to readjust between 300 and 360 rpm.

Of course it would have to be be able to do the math.
