Thanks welovetim. This works!
I was also looking for the same solution. Apparently it doesn’t create duplicate content. Check this http://www.wplover.com/760/wordpress-short-url-using-post-id-plus-its-effect-on-seo/
i mean the css for the content/php part of the ‘Pages’ is not loading, everything else like header, footer, sidebar is loading properly.
