I personally think this is a really good idea however, I wouldn't remove the comment system.
I'd like Wordpress to be more flexible than it already is. I see websites like The Verge and Polygon, how they have different styles for different kinds of posts. They create beautiful reviews, very magazine-esque, how it's supposed to be. Giving this amount of control the users would allow authors to be a lot more creative and create even more beautiful and better websites than ever before.
