Unless you are really short of disk space, what's wrong with copying the
complete package directory - it makes life much simpler.

If you just want to add a patch, you can do it with bashrc, no need to
mess with overlays: http://forums.gentoo.org/viewtopic-t-339019.html

There's a script floating around that will copy an ebuild to your overlay
and bump its version. Adding patches is easier with bashrc. But neither
of these are related to the original question, which was about
preserving old versions. for that you only need at most one mkdir and
exactly one cp.
