The Watchtower would not get permission, to begin with, to connect a copy of the New Testament to an already existing published Hebrew version of the Tanakh. Why?
While Jews are not forbidden from reading or owning the New Testament, putting the books together like that would not be allowed by Jewish law. The combination creates the Christian canon, which was created by Christian church authority which Jews are not subject, nor is Jewish scripture.
Next, all Jews already have a copy of the Hebrew text of the Scriptures. We have parts of it memorized, pray the psalms during the day, have portions nailed to our doorposts behind mezuzahs, have sections of it in our siddur (prayer book), have it in a giant scroll form in our temple of synagogue--we got more Bible in Hebrew than the Watchtower has in any language. Remember, JWs are just readers of the Bible compared to us. We're the people who wrote it.
Third, most Jews want nothing to do with the New Testament or Jehovah's Witnesses because of what they are doing to us: proselytizing. Proselytizing is telling a people that their way of life is wrong, that their culture and identity is wrong and must be changed, that the way the express themselves must stop, and idemands in the name of religion that that they make changes or be destroyed (usually by God).
If a Jew is to become a Witness, they would have to stop observing the Jewish Sabbath, Passover, Jewish men would have to stop wearing kippahs on their heads when they pray, most would have to shave their beards, and basically we would have to stop most of our customs and adopt Jehovah's Witness standards...which by the way are Western customs built upon paganism from our point of view.
Without these things we would lose our cultural identity, and that would mean the destruction of the Jewish people if we all did that. That is why Jews see proselytizing as anti-Semitism. To us, and to many non-Jewish people, it is evil, as evil as the Holocaust.
So the idea of producing such an item for proselytizing the Jews to make us non-Jews who no longer celebrate Jewish holy days, who no longer grow long beards, who no longer support a Jewish state, who no longer wear yarmulkes when praying...no, there is no difference between destroying us this way or destroying us via gas chambers and ovens.
So my recommendation is to not even try and to separate yourself from any organization or group that believes a culture, any culture, should be totally altered in the name of some religion or God or face total destruction for refusing to do so.
Sometimes swastikas come in the shape of watchtowers.
