Copy wrapper.php to own template for changing

I propose to change code
/wp-content/plugins/goods-catalog/inc/class.wrapper.php:18

if ( is_post_type_archive('goods') || is_tax('goods_category') || is_tax('goods_tag') || is_singular('goods') ) {
		    if (file_exists(GOODS_CATALOG_PLUGIN_TEMPLATES . '/wrapper.php')) {
		        return GOODS_CATALOG_PLUGIN_TEMPLATES . '/wrapper.php';
		    }
		}

to

   if (file_exists (get_template_directory() . '/wrapper.php')) {
                // echo 'Current template: ' . get_template_directory() . '/' . $template;
                require_once (get_template_directory() . '/wrapper.php');
            }
            elseif (file_exists(GOODS_CATALOG_PLUGIN_TEMPLATES . '/wrapper.php')) {
                return GOODS_CATALOG_PLUGIN_TEMPLATES . '/wrapper.php';
            }

for ability to copy and change wrapper.php to own theme folder.
