No it's not possible.  Adding nbi support to grub is possible but not

The problem is that grub uses the whole low memory area for its own
purposes; nbi only reserves two small low memory regions for the boot
loader.  Of course one can do a similar trick as we already do for
linux zImage, i.e. load everything to high memory and copy it to low
memory just before booting.  It needs a bit of smart memory
organization though, as nbi images can also require some parts to be
placed in certain high memory regions.

Another way to add nbi support would be to write a multiboot
compatible nbi loader :)
