Yes, I know this is possible, especially if you feel like running the book quest 8 or so times. My question is... What happens at that point? Does the game pull a FO3 and lock up? Searching on the internet indicates that it will, but that was in conjunction with directly editing a save, so it may not apply if I do it the "normal" way.

--Edit-- Sorry for typo in the title. Damn autocorrect, and no way to fix it.
