There's no need for that. You're pretty unlikely to break init upgrading
your kernel, and a statically linked copy is fairly unlikely to save you
if you do.

Far better is to always keep an older kernel around that you can boot in
an emergency.

If you _do_ manage to break init and are unable to boot your system, it's
worth knowing that if you take init away altogether the kernel will just
run a shell for you.
