Take a look at this solution:

How about adding 4 Gotek (or clone) drives? Apparently, you can define a drive type of up to 255 tracks, some number of sectors, another number of bytes/sec. Adding some static ram beside the ROM will suffice for sector buffers in my mind. Of course, that will mean hacking the BIOS...
