ISO: Auto Importer for HTML

This is a long shot, but I’m at the end of my search rope.

I’m trying to set up a documentation website that automatically pulls information in from html files. The documentation itself is written in ReStructuredText, and uses Sphinx to convert those RST files into HTML (which are then published as is, in an awful-looking site). In a perfect world, there’d be a way for me to tell WordPress to look for new versions of those html files, and import them into WordPress as new pages.

Am I crazy? Or is there a way to do this? I’ve looked at HTML Importer 2, and it’s not quite what I need.
