Perhaps this helps:

	/usr/bin/gri -> /etc/alternatives/gri -> /usr/bin/gri-some-version
	/usr/bin/some-other-gri-bin -> /etc/alternatives/...
	/usr/bin/gri-version-a
	/usr/bin/gri-version-b
	/usr/bin/some-other-gri-bin-version-a
	/usr/bin/some-other-gri-bin-version-b
	/usr/lib/gri-version-a
	/usr/lib/gri-version-b

I guess I'm asking: does gri-version-a really NEED to replace gri (or the
other way arround)?

gri (<some-version>) should conflict with gri-<some-version>, like this:

Package: gri
Version: 3.14
Conflicts: gri-3.14

Package: gri-3.14
Version: 3.14
Provides: gri

Of course, gri-version can't satisfy "Depends: gri (>= version)" because we
don't have versioned provides.
