Thinking further ... if I were going to design such a book, I would want to do it in two-page "spreads" that had a bunch of related stat blocks, and then the descriptions of any powers they all had in common. Each "spread" would be kind of self-contained.
So I might have a two-page spread featuring Ogres, with stat blocks for an Ogre Cheiftain, an Ogre Champion (maybe a fighter or whatever martial class you wanted), an Ogre Adept or Cleric, an Ogre Barbarian, and a couple of different styles of Ogre Warrior, and make it fit on one two-page spread so you could lay that book open and have it available for when the PCs are raiding an ogre lair. If you had room you could do brief stats for typical ogre pets and ogre lair traps.
