This is a great idea for an addon. I've rewritten the core theme about 5 times since we started development on Vanilla 2. However, with the official release this summer it made it impossibly hard to do any more changes to it. I've wanted to change a ton of the html in the views for a long time to make it more SEO friendly, but it would break so many people's custom themes that I just can't do it. Nice to see others working towards that goal!
