It's not possible, yet. 

It would require loading the disk image into memory and adding a small
bios hook that maps accesses from floppy to the memory image.  This is
what etherboot does.  AFAIK, nobody has written such code for grub
yet.

We could also add netboot image support do use the netboot floppy
images (that contain the bios hook).  But this would require shuffling
memory blocks, as netboot assumes that the boot loader needs much less
space than grub does.
