You could "cheat" and instead of storing the sha1 of a blob object in
the notes tree, use the lower 32 bits to store an actual value. I don't
think that currently breaks any assumptions in the notes code, but it
definitely is against the intent of it.

I highly suspect that it would break fsck rather badly.  You may not even
be able to repack a repository with such a notes tree.

Well, we could (ab)use file mode to mark that what would be sha1 actually
stores fixed-width content of a file, like we do with submodules.

This technique is I think quite similar in idea to filesystems storing
contents of small files in file inode, isn't it?

Are the benefits really worth all these hacks?
