Why not, it should just be an image in ascending order of 
(track,sector), 256 bytes per sector.

The cbmlink software by me includes a disk image reader, which basically 
increments the sector and track counters until an illegal track or 
sector is reported, and then steps to sector 0 on the next track, or 
ends copying when the track number becomes invalid.

I hope that the WMUTIL.PRG does the same.

It should not be too hard to modify cbmconvert to support D9090 images.  
There is only a single directory, right? And the maximum file system 
size is 255 tracks, 256 sectors per track, 256 bytes per sector, right?  
That would be a bit under 16 megabytes (16 MiB - 64 KiB).

I could actually be interested to do this; it has been a while since I 
updated the tool. :)
