If we had access to the original Bible, would we still need the Qur'an?

I am willing to accept the argument that one shouldn't trust the bible as it has been changed so many times. There are many inconsistencies in the bible, but what if we had the original bible? What if we had access to the original texts, would we still need the Qur'an? I mean Why debate when all we need to do is go to the source of the text.
