It might not be a bad idea, especially since MMIX is well documented and
fairly simple.  

However, since it doesn't have real devices (Just traps to do OS-like
things), it'd probably be good to have a simple CPU with some simple
devices so newcomers can copy it as a starting point for other projects.
