The interesting things you would get from Grub would be the 
filesystem-decoding stuff, the elf decoder, the two-stage loader, and 
the nice and well-tested config-file parsing, in a format that lots of 
users already understand. Tftp and bootp/dhcp support could also be nice 
in some scenarios.
And by having the bootloader in the domU you would get stronger security 
as well.
