Hey, so I've been hacking this around for the past half hour. I know it's not finished and lacks many features of the real redesign.. I may finish this later (or if you want to, you welcome to do this).

The userstyle: http://userstyles.org/styles/64417/hacker-news-redesign?r=1335017938

(p.s, sorry for my English.. Greetings from Israel)
