That's, more or less, what the second chance pool attempts to do. As do subcategories like https://news.ycombinator.com/show which effectively extend the 'visible time in queue' for Show HN posts.

I think the underexamined assumption in a lot of these analyses is that it's hard to get a post on the HN front page. But in reality, it's relatively straightforward with a whole pile of backup mechanisms. The mystique of 'magical posting hour' draws people in but it's a lot simpler to just produce a post that matches HN's (fairly broad and loose) interestingness criteria.
