Usually things turn ugly - used to be that portage saw that there are two glibcs installed and unmerges one (oh crummy, you only had one? better reinstall now ...) and other really disturbing side-effects. Just unpacking a stage3 over a live system is a nice game, but rarely has sane results. You'd need to use a VDB-aware tool like qmerge to do it cleanly, and then you still don't have a working system (new glibc on old kernel, new udev on old kernel, lots of situations where things don't work out)
