gopages: output markdown format (via custom template?)

In my repo I'm using MkDocs to generate a gh-pages site based on the documentation I have in Markdown format. I would like to integrate the godocs within that documentation. Would it be possible to support a custom template for the index files so instead of generating HTML I could generate Markdown instead?

I could probably get MkDocs to include the HTML files, but supporting Markdown would ensure the theme and formatting stays consistent with the rest of the documentation.
