Sure, its very doable. This is how I upgrade most of my systems. don't
mount /mnt/clfs on a seperate partition. and you can leave the symlink
to /tools or move /tools to the host once you're done. After that just
boot with init=/tools/bin/bash . After you're booted in run this:

export PATH=/tools/bin
set +h
mount -o remount,rw /

You should be free to replace any file on the host system at that point,
as if you had just entered the chroot environment.
