And to answer my own question 🙂 in case anyone else is trying to figure this out..

add_filter('img_caption_shortcode', 'gn_caption_shortcode_filter',10,3);
function gn_caption_shortcode_filter($val, $attr, $content = null)
{
	extract(shortcode_atts(array(
		'id'	=> '',
		'align'	=> 'alignnone',
		'width'	=> '',
		'caption' => ''
	), $attr));

	if ( 1 > (int) $width || empty($caption) )
		return $val;

	if ( $id ) $id = 'id="' . esc_attr($id) . '" ';

	return '<div ' . $id . 'class="wp-caption ' . esc_attr($align) . '" style="width: ' . (int) $width . 'px">'
	. do_shortcode( $content ) . '<div class="wp-caption-text">' . $caption . '</div></div>';
}

Thanks, I just posted it there.
