The concept of the book seems great on paper, until you really think about it. What you are really asking for is a concise book of NPCs that are what you have in mind at any given time. To illustrate the point, how about a book with devout zealot humans who all worship a LG God? And some serious gnome inventors who are rather dour but talented with brass goggles. And, why not? Some "Hobbits" (halflings), who are all farmers and naive. And let's throw in the drunk, gun wielding, crazys who live "under the mountain". Just as fun and flavorful, but perhaps not what you're looking for (Tolkien-land with guns and steampunk gnomes).
And that's the problem. Beyond picking a single stereotype for each race (elven woodland archers, greedy dwarf miners, etc.), you run into the problem of which stereotype to pick. The most useful answer would "pick all" which makes more combinations than stars in the sky. I like the fact that Paizo hasn't pushed a cannon stereotype for each race, as previous editions have done.
I'm going to echo Brother Fen's advice of trying to make what's out there work, or get HeroLab (or something similar), or do it the old fashioned way. While it doesn't hurt to ask, I wouldn't hold out for a book that may never come.
