Combine multiple plugins into one?

I’ve collected a few plugins that each have specific functionality I need for what would otherwise be a single large plugin.

Is it possible to bundle these into a single installable zip?

1. Go through each plugin file and remove the plugin header.
2. Create a loader.php file.

Something like this:

<?php
/*
Plugin Name: Combined Plugin
Description: Contains plugin a, plugin b and plugin c
*/

include dirname(__FILE__) . '/plugin-a.php';
include dirname(__FILE__) . '/plugin-b.php';
include dirname(__FILE__) . '/plugin-c.php';
