Sphinx does appear to have translation support:
http://sphinx-doc.org/intl.html?highlight=translation

I've never used the feature myself, so I don't know how good the workflow is.

Sphinx will generate PDFs, though the LaTeX output is not as nice
looking as what we get now. There's also a direct-to-pdf builder that
uses rst2pdf that appears to support templates, so that might be an
easier path to producing something attractive:

I'm not sure this quite answers the question, but the RST directives
for auto-generating docs from code usually depend on being able to
import the code. That means heat and its dependencies would need to be
installed on the system where the build is performed. We accomplish
this in the dev doc builds by using tox, which automatically handles
the installation as part of setting up the virtualenv where the build
command runs.
