Hey, it's been a while since I've done any Oblivion modding and I was trying to remember if there is a floating point setting to change that changes the exp/use for restoration and destruction so that they level a bit quicker. I've scrolled through the list a few times but have found nothing, just wanted to check here before I give up on that.

Can't help you on how to do it but examining Tejon's http://www.tesnexus.com/downloads/file.php?id=14304 mod would show you the way.

You'd just edit the skills themselves under Characters --> Skills. Raise the Use Value to increase the exp gained per use. That's it.
