Yep, it is possible to make nearly anything (maybe everything) work if
you present what appears to be a standard FDC to the CoCo.  For
instance CoCo3FPGA uses a second processor to speak DriveWire behind
the scenes but look like a completely normal FDC to the CoCo.  There
has also been talk of adding this functionality to the DriveWire
support in VCC.  Darren Atkinson had a controller that did this in a
real CoCo.  This used the DMK format to support every operation of the
WD floppy controller, something standard DriveWire does not do but
could easily be extended to support.
