Header / Footer over to a WP blog

I am about to set up a news / blog site for our primary site, FlareAware.com. I’m looking for a solid theme that will cary most of the stylistic elements over, yet allow us to customize the header and footer satisfactorily so that it matches the current Rails web app style so that it does not offer such a jarring experience whilst moving from the main site to the news site. Do you have a particular them that would be most useful in this respect?
