National OW Series?

I talk about this more in-depth on my personal blog (not the blog in the USMS area, but the one below my sig block), but wondering if there is interest in having some sort of national OW series, similar to H2Open (magazine)'s new National Series. I envision something like "most well-rounded" where you swim one event in each of three categories (1K to 4.9K, 5K-9.9K, 10K and up), then you're ranked with others in your age and sex range. What say you?
