Genesis - Adding custom hooks to display secondary navigation

within my functions.php I added the following piece of code to display my footer accordingly:

//* Customize the entire footer
remove_action( 'genesis_footer', 'genesis_do_footer' );
add_action( 'genesis_footer', 'my_custom_footer' );
function my_custom_footer() {

    ?>
    <div class="site-footer-logo">
        <img src="<?=get_stylesheet_directory_uri();?>/images/my-logo-small.png" alt="My Logo Small" />
    </div>
    <p>Copyright &copy; <?=date('Y');?>, my-url.com.</p>
    <?php
}

I want to have the secondary navigation menu displayed between the div .site-footer-logo and the following paragraph. Can i just add something like do_action('my_own_hook'); and then access it via add_action( 'my_own_hook', 'genesis_do_subnav' ); ?

Is this 'allowed' in the Genesis world?

Thanks.
