Load object "userViewUser"?

-- HikaShop version -- : 2.6.0
-- Joomla version -- : 3.6

In my shop config I have: Registration->Guest

I want to offer also my users to pay as guest but also to register. To do this I copied the file registration.php in "/templates/my_shop/html/com_hikashop/user",

In the "/templates/my_shop/html/com_hikashop/checkout/login.php" I tried to call the registrationNEW.php with following command:

$usersConfig = JComponentHelper::getParams( 'com_users' );
			$allowRegistration = 1;
			if($allowRegistration || $this->registration[3]){
				echo hikashop_getLayout('user','registrationNEW',$params,$js);
			}else{
				echo JText::_('REGISTRATION_NOT_ALLOWED');
			}
