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).
