Cross environment relationships is on the "everybody wants this done

Instance density is on the "everybody wants this done a year ago"
TODO list. :) There is agreement that it is needed, and it exists in
hackery-form for the python version in juju-jitsu (see: jitsu deploy-to).

The (deprecated) python version has a REST API which the Juju GUI
uses. juju-core will in theory have one "real soon now" but probably
not until after 2.0 is released.
