Possible to change the CKEDITOR Skin?

[Xarwin]

Hello there.

I'm working on a new layout for my vBulletin and was wondering if it is possible to change the CKEDITOR skin to something else?
I've tried a few things such as adding config.skin='minimalist,/clientscript/ckeditor/skins/minimalist'; in some various ways to ckeditor_config.js (located in clientscript) but it didn't seem to work at all.

The CKEDITOR has some skins here: http://ckeditor.com/addons/skins/all so I'm wondering, if it is possible to change it?

Thanks in advance!
