Not sure if a rising sort is really needed. A link only needs a few points to get on the front page of HN. Based on my experience if a link gets 3 votes in the first 15-20min or 5 in an hour and it'll get some frontpage time. I think it may almost be easier to just show a random new link from the past hour rather than doing anything fancy. I'm sure a ton of good content misses the frontpage just because of the sheer lack of visibility that links on the new page get.
