Header and footer from CI + posts from WP

No, I just want WP as a nice backend for people that will write content but theming would be cool to do with CI.

So, is there any way to stop WP's routing within /blog/ directory? I tried creating a controller and a view in CI but it seems like WP takes presedence and renders the pages in that directory.

Thinking about it now, could I just remove the index file in /blog/ directory? Would that be a way of stopping WP's routing?
