Thanks not just for this, but for all your thoughts about this topic, which I find most intriguing.
I suppose my hesitations are:
1) "Cannot" is a stronger word than I'd be inclined to use. In reality the article is often missing, as a quick computer search will reveal, e.g. (to take incontestable "book" names) εν βιβλω λογων ησαιου (Luke 3:4), εν βιβλω ψαλμων (Luke 20:42), εν βιβλω των προφητων (Acts 7:42, already cited), etc., etc. In the present case there are several plausible reasons for avoiding use of the article, e.g. the desire to avoid the jingle τω... τι.
2) Acts 7:42 also shows that (at least in some manuscripts) Hosea, like Elijah, wasn't a βιβλος in those days (just a section in the βιβλω των προφητων).
3) In addition, I doubt whether there was a very fixed boundary between "βιβλος" and "passage." That might have varied; for instance, different copies of the prophets might have occupied a different number of βιβλοι.
