Hi there! Yes, you can use a child theme and CSS to do this. I recommend using Firebug for CSS work–makes it much easier.
You’d want to copy the theme’s header.php and footer.php into your child theme, and move the menu from footer.php to be within the blackbar div in header.php. Lines 28 – 41 in footer.php create the navigation menu, you can probably remove the search component unless you want to keep it.
Then you can style the menu how you like in your child theme’s style.css. I don’t offer advanced CSS customization support, but the links above should get you started. Good luck!
