It won't work.  El Torito actually only fakes a floppy if you're using
the legacy floppy emulation mode.  These days we use the more enhanced
mode which lets you use larger than 2.88 MB images.  And, unfortunately,
unless you boot from it, the BIOS has no way of accessing the CD drive
and thus, neither does grub.
