Good question. I was able to make the whole admin RTL with a little plugin (I wrote it as a must-use plugin, but should work in the in the standard plugin folder as well). It’s a very simple version, see the output here:
This is the plugin code (my file-name: rtl-admin.php):
<?php
/**
* RTL Admin WordPress Plugin
*
* @-wp-header Plugin Name: RTL Admin
* @-wp-header Author: hakre
* @-wp-header Version: 0.1
