If anyone cares (and they probably don't, but whatever), the way I read it the time I did it in a year was to read the entire Hebrew Scriptures first, but not in Christian Bible order, but Hebrew Bible order (first the Law, then the Prophets, then the Writings). Then I read the 7 undisputed letters of Paul, then Mark, Matthew, Luke, Acts, and John. Then James, Hebrews, and the rest of the Pauline corpus. Then the rest of the NT Epistles, and lastly Revelation.
But for something like what we are proposing here, for a large number of people (both believer and non-believer) reading through the Bible together, we should all follow the same schedule, and probably the given order of the Bible would work the best.
