There was already a bit of a start with Sulla's brand spanking new Tabularium (I forget if it was perhaps called by some other name), which tried to include the Republic's entire legal text and historical legal texts, as well as all of the most important (for state function) Latin works. Expand this to include any Latin, Greek, and perhaps even Egyptian, Persian, and Gallic works of law, poetry, mathematics, etc., and that's a wrap. It would take decades to implement due to the difficulty of gathering originals or even copies of all those works, but it can be done.
