I think that's what mes-m2 rewrite [1] (not to be confused with mes wip-m2 branch)
is trying to achieve.

Outside of Guix we are working on bootstrap that does not depend on guile driver
and is driven only by hex-0 seed (357 bytes) kaem-optional-seed (737 bytes) and any POSIX
kernel.

At the moment it goes all the way up to Mes (tcc is now in progress).
