Unregistering Parent Theme Sidebar

Hi Folks,
I’m working with a handy responsive theme framework (Reverie) and I’m developing my own theme the right way using a Child theme. The Parent theme calls a sidebar called with an ID of ‘Footer’ and applies some basic styles to it. I want to adjust this in my child theme, so I was looking at perhaps filtering it but in the end I decided it’d probably be easiest to unregister the sidebar and re-register a new one with the proper classes in childtheme’s functions.php.

Yet, I’m not able to de-register the sidebar. I’ve attempted it, with the code below, but without any luck..

// Unregisters Reverie footer sidebar
function remove_footer(){
	unregister_sidebar( 'Footer' );
}
add_action ('widgets_init, remove_footer', 11);

// Registers new footer array with proper classes

$sidebars = array('Childfeet');
foreach ($sidebars as $sidebar) {
    register_sidebar(array('name'=> $sidebar,
    	'id' => 'Childfeet',
        'before_widget' => '<div class="small-12 medium-6 large-3 columns"><article id="%1$s" class="panel widget %2$s">',
        'after_widget' => '</article></div>',
        'before_title' => '<h4>',
        'after_title' => '</h4>'
    ));
}

My new sidebar with proper classes is of course created, but it seems like my remove_footer() does not do it’s job. Any ideas?

Thanks very much!

Addition: Just so you can see the footer I’m trying to remove, here is it’s declaration in the parent themes functions.php

$sidebars = array('Footer');
foreach ($sidebars as $sidebar) {
    register_sidebar(array('name'=> $sidebar,
    	'id' => 'Footer',
        'before_widget' => '<div class="large-3 columns"><article id="%1$s" class="panel widget %2$s">',
        'after_widget' => '</article></div>',
        'before_title' => '<h4>',
        'after_title' => '</h4>'
    ));
}
