Thank you!
This helps me a lot.

I found a generic way for my project:

/**
 * Plugin dir
 */
define('IRM_WOOCOMMERCE_VARIATION_SWATCHER_DIR', plugin_dir_path( __FILE__ ));


/**
 * Override WooCommerce templates from your plugin with child theme way
 */
function irm_woo_locate_template( $template, $template_name, $template_path ) {
	$re = '/woocommerce\/(templates\/)?(.*)/m';
	preg_match($re, $template, $matches);
	if(isset($matches[2]) && !empty($matches[2]) && file_exists( IRM_WOOCOMMERCE_VARIATION_SWATCHER_DIR . 'woocommerce/' . $matches[2] )) {
	    $template = IRM_WOOCOMMERCE_VARIATION_SWATCHER_DIR . 'woocommerce/' . $matches[2];
	}
	return $template;
}
add_filter( 'woocommerce_locate_template', 'irm_woo_locate_template', 10, 3 );

After that, you could use the official way.

Of course your way more optimal for the best performance.
No doubt of that.
