Have you seen HxC?

Yes, I believe I posted a link to it. But understand, that it's not
a "know nothing about the floppy, just stick this thing in and go"
type of device. Software must be coded to accomodate the recording
method and organization that you're using.
I have to laugh when people use the term "GCR" as if it were a
standard. My response is usually "whose GCR?".
Personally (and professionally), I'm less concerned about emulating
floppies than retrieving data from them and allowing people to move
on. The world in general seems to have been pretty successful in
weaning itself away from 556 BPI 7-track 1/2" tape, after all.
There is a lot of data still residing on obsolete and obsolescent
media. The great part is that once the world migrates from one
obsolete medium, there's always another to be declared obsolete.
So when will mechanical hard drives be on the chopping block? If you
think about it, they're really a backward technology, with moving
parts and hungry power consumption.
I had a potential customer who wanted to replace an old AMD multibus
floppy controller board with a modern version that would support high-
density 3.5' floppies, needed to boot his system, but not otherwise
used to hold working data, I tried to point out to him that it would
be far simpler to employ an EEPROM with the needed data.
He would have none of it. He also specified that all parts had to be
through-hole and socketed.
