New Address in checkout

-- HikaShop version -- : 2.5.1
-- Joomla version -- : 3.4.6

Dear Sir
during checkout, if the customer do not have address, a message will be displayed asking to "Please create or select an address", I want change this to display the new address form instead, I know where to edit but could not figure what to code to put
in checkout/address_view.php.
I see the below IF statement which I want to replace with the display address form and pass the required parameters to it:

if(!JRequest::getVar( HIKASHOP_COMPONENT.'.address_error')){  
JRequest::setVar( HIKASHOP_COMPONENT.'.address_error',1);
$this->app->enqueueMessage( JText::_('CREATE_OR_SELECT_ADDRESS'), 'error' );
	}

Hello,
I didn't totally understood what you wanted to do, can you give us more information about it through some screenshots for example ?

I know you have the above behavior if I select List as Address selector, but am forced to keep the popup as Address selector as I need the address to be in full page.

Dear Sir
thanks for your fast response
I just need to replace that message by the address form and to be in the same page when there is no address
attached is 2 screens shot , the before.png is the current situation, and after,png is what I want to achieve
