[gentoo-embedded] How to manage multiple distributions, cross compilers in one chroot environment

Hi,
Continueing the discussion started by my last thread "CBUILD= HOSTCC=-gcc",
I said I want to compile a cross compiler with a special name.
I wanted i686-gentoo.edge-linux-gnu but it is possible to do just
i686-pc-linux-gnu

I did this because crossdev creates some magic setting up things, and it is
very handy.
What I want is a way to keep few compilers environments.
lets say:
stable x86 compiler
unstable x86 compiler
few arm cross compilers.

So when I create a distribution and an few month time I want the same
exactly environment,
to compile and upgrade few packages and be sure not to break anything, I
want to keep
those version of the compilers.

I'll also need some way to have few forks of my initial system.
lets say:
emebedded board 1 - for customer A
emebedded board 1 - for customer B (it is different than A, by time of
creation and so by version of the compiler used).
emebedded board 2 - for customer C

Can we boost up crossdev, or I need to start hacking a distro_creator
utility for gentoo?

Regards,
Kfir
