Though I don't have a 5.25" drive for it -- I did have > CrossDOS to read MS-DOS, and I think CP/M format floppies. That was true of almost all 5.25" drives, including those in the early IBM PC's. We had a program that wrote some 200 different CP/M 5.25" disk formats. (Why there were so many never made much sense.) I know we sold compilers on many of those formats. [I wrote such a program in my early days; programming the disk controller chip was relatively easy and the most important thing was making sure that the data got dumped to the controller fast enough.] However, the Apple II with its variable speed drive motor was not one of those. The only way to copy disks for an Apple II was to use an Apple II. (We used a friend's Apple II; we had to buy him a new disk drive after wearing out one copying a thousand or so disks.) Probably someone did that commercially, and that would have made more sense if we hadfound them, but that was nearly impossible in those pre-Internet days -- you never found out about anything unless you saw an article or ad about something.
