Interesting thought on a possible new use for an old concept. When I was working at a newspaper, the inverted pyramid style was used for two reasons: to give readers enough info right away to get them interested in the story (or decide they're not interested, and go on to the next article), and to be sure the most important part of the story actually made it into the paper - You never know where someone on page layout is going to have to slice off the end of your article so it will fit. (That's why it's a continuous pyramid and not just a sharp drop - Most important info in the first paragraph, next layer of importance in the second, and so on to the end of the article.)
