Please delete this thread as I have found a much more effective way of doing this with hacking. Thanks. :)

One thing I just noticed, and this only applies if you change your style everyday, and most people don't, if you update the CSS in the admincp, it renames your CSS file, so you will have to update your headerinclude to reflect this change.
