Magento 2 - New custom URL for custom checkout page - magento2

Question

I need to create new checkout page with new url and need to show my custom address fields in that custom checkout page.
My way is :
Create new custom checkout module ( CustomCheckout )
Create new route ( like custom-checkout )
Copy and paste the checkout_index_index.xm layout in my custom
checkout module
Is that correct way ? pls give a solution ?
/etc/module.xml
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
<module name="Mymodule_CustomCheckout" setup_version="0.0.1">
</module>
</config>
/etc/frontend/di.xml
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">
<router id="standard">
<route id="customcheckout" frontName="customcheckout">
<module name="Mymodule_CustomCheckout"/>
</route>
</router>
</config>
Controller/Index/Index.php
namespace Mymodule\CustomCheckout\Controller\Index;
class Index extends \Magento\Framework\App\Action\Action
{
public function execute()
{
$this->_view->loadLayout();
//$this->_view->getLayout()->initMessages();
$this->_view->renderLayout();
}
}
/view/frontend/layout/customcheckout_index_index.xml
//Copy and paste checkout_index_index.xml from magento-checkout module

Answer 1

You can acheive this by simply add before attribute in module tag.
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">
<router id="standard">
<route id="checkout" frontName="checkout">
<module name="Mymodule_CustomCheckout" before="Magento_Checkout"/>
</route>
</router>
so magento then call your custom checkout route instead of core checkout controller.
so accordingly you can change the layout and all.
