No, they have not. The Old Testament points to Jesus, and they deny that he is Lord and God.
There is no reason to believe this. These are the same people who rejected Jesus as Lord and God, when he performed miracles right in front of their very own eyes. There is no reason to think that they would accept all of God's word, because they rejected God himself. And as we agree that they rejected at least 27 writings that are the inspired word of God, there is no reason to think that they would not reject 7 more, especially ones that contain explicit prophecy about Jesus, such as found in Wisdom 2.
Yes, at least at one point in time St. Jerome doubted the that the Deuterocanonical books belong in the canon. But he later changed his view and assented to the teaching of the Church, after he was corrected.
