Creating A footer2.php File

I’ve been working on a theme, but I realized I will not want my nice big 4 column footer widget area on all pages/templates. So I just saved a footer.php with the basic credits and info, and thought I could create a footerWidgets.php that I could just drop in <?php get_footerWidgets(); ?> on templates where I do want this widget area.

But that is obviously missing some programing/php/functioning/stuff I don’t know about. Is there any easy way of creating new site section php files that WordPress will recognize?

Thanks.
