I do recall seeing somebody's project over the past few weeks. It did this, pretty much. I can't recall the URL, but it had three or so iframes - one with HN article listing, one with the page destination and another with comments. Personally, it ended up being a worse experience than just using HN as it is. I do agree, though, that target="_blank" would be a very nice addition.
