I find this very interesting. The two alternatives that exist currently
(or, at least, that I know of), namely (a) installing in the MBR (+ the
following sectors), or (b) using block-lists, have well-known shortcomings.
With your solution, one could simply write the boot sector in an ext2
partition's boot record, and put GRUB files in the ext2 filesystem.
Whatever is in the MBR would then simply chainload the ext2 partition.
Is this correct?
