docutils.core.publish_parts isn't designed to handle doctree input;
docutils.core.publish_from_doctree is. You may be able to get the
results you want, but I'm not sure. Compare publish_parts and
publish_from_doctree, and note the source_class and parser_name
defaults. You'll have to match the publish_parts parameters to the
values used in publish_from_doctree.

If you can't, you'll have to roll your own.
