Definitely. Keep in mind, they'd need to sell a lot of units to justify printing a book. That's the hard part IMO.
If put together well...instead of just a picture book, maybe make this 'book' I historic look at Wacky Packages. Each series can be a different chapter, with master lists/photos, artists bios, trivia tidbits on rare items, legal issues, etc. Photos could include actual products, wacky product, and maybe even early sketch evolutions of said wacky. Other interesting wacky items to discuss in the books would be spin off items like ad sheets, early cooperate letters, clothing, towels, die-casts, milk caps, puzzles, etc.
