It's sounding like the nearly the optimal solution would be:
/var/cache/portage/distfiles
/var/cache/portage/repositories/gentoo
/var/cache/portage/repositories/{sunrise,kde,gnome,whatever,layman,grabs}
/var/db/portage/repositories/{non-cache,repo,names,go,here}
Clearly, some data in question needs to be treated as persistent, and
others can be treated as cache. So it should probably be divided up
that way. The placement of tree and overlays as subfolders of the same
folder strikes me as appropriate, too.
The only thing I can't see an elegant workaround for are how to avoid
or handle repo name collisions between
/var/cache/portage/repositories/* and /var/db/portage/repositories/*
