Cron jobs in wordpress, without wp scheduler

Hey guys, I want to setup a cron job on my server (via crontab) that hits a script which requires the wordpress-environment to be loaded in order to work.

My current solution looks like this: I’m triggering a php script which requires ‘wp-load.php’ and kicks things off via triggering a hook using
do_action('stuff_that_happens_when_crontab_hits') to which the actual code that needs to be executed listen within a add_action('stuff_that_happens_when_crontab_hits', 'the stuff')of course. I also disabled the cron implementation of wordpress define('DISABLE_WP_CRON', true);

The crontab entry looks like this:

0 * * * * /var/www/wp/mywpcron.php

This is the file that gets hit by crontab:

#!/usr/bin/php
    <?php
    if (php_sapi_name() !== "cli")
            return;
    require 'wp-load.php';
    do_action('stuff_that_happens_when_crontab_hits');

Does this seem legit or am I overseeing any negative repercussions? Any input would be grandly appreciated!
