So If anyone else stumbles upon this
it can be achieved using WordPress multisite feature
just add
/* Multisite */
define( ‘WP_ALLOW_MULTISITE’, true );
You can follow this awesome tutorial here
to your wordpres config file (wp-config.php) and you will have a working installation , all you have to do is to copy the categories from core to your target website and activate the theme on main site.
You probably won’t have customizations but I will post as soon as I figure out how to do that.
