Separate footer.php files for exhibit theme?

I'm currently working on a custom exhibit theme, and I was wondering if there's a best practice way to call different footer.php files for different areas. For example, I'd like the main theme to have one footer most places, but I'd like exhibits to have a different footer. Would placing a footer.php in my exhibits folder in my theme override the common footer.php? Thanks!

Never mind. For a minute there I didn't realize foot() has a $file option. Case closed.
