Update Data parameter of a localized script in Wordpress

I'm working in a child theme, In my-page-template.php I have :

//...
$id_curr= 5;
wp_localize_script('my_js', 'ajaxload', array('post_id' => $id_curr)); 

In my_js.js I have an AJAX call :

$.ajax({
   //...
   type: 'post',
   data: {
      action: 'ajax_load',
      post_id: ajaxload.post_id
   }
})

---

Now in functions.php, I want to edit/update ajaxload.post_id. Is there a way to do that? If I try re-calling wp_localize_script() with the same $name as shown below, will this work?

$id_new=8;
wp_localize_script('my_js', 'ajaxload', array('post_id' => $id_new));
