YHWH in Ancient Rome?

Okay, I might be going a little out in left field with this one, but I thought I would bring it before you and see what you all think of it. Anyone who has studied biblical or ancient history has invariably come across a whole genre of quak-historical studies having to do with theories of where the Ten Lost Tribes of Israel vanished to. You know what I'm talking about...the "British Israel" theory, that the Irish and original British were displaced Israelites (and that the prophecies and promises made to Old Testament Israel apply to the British Empire, and by extension, to the United States, which had its origin in the British Empire). Some say the Israelites sailed across the Atlantic and became the Mayan peoples...there are ethnic groups in India, southeastern Asia and Ethiopia that all claim descent from Israel's Ten Lost Tribes; of course, the Mormons have their own absurd take on this theme. There is even a theory that the Lost Tribes had something to do with Atlantis.

Therefore, please take what I am going to say with a HUGE grain of salt, because I am in no way wedded to this theory that I am about to propose. I merely noticed something and am interested in some feedback.

First, we know that the ancient Israelites, whether the ten northern tribes or the southern tribes of Judah, did not pronounce the name of God. They considered it too holy, choosing instead in speech to replace His name with phrase like "heaven" (as found in Maccabees) or more simply LORD, as found in most of the Old Testament. In writing, the holy Name was usually written in the form of the Tetragrammton, which consists of the four consonants of God's Name with the vowels removed so as to render in unpronounceable - the Tetragammaton in Hebrew is, יְהֹוָה,which is translated into English as the consonants YHWH. Though nobody knows how the Holy Name was pronounced, most Hebrew scholars believe it was close to "Yahweh."

This much really isn't in question - but now let's look at the ancient Roman connection. The three supreme deities of the Roman pantheon were Jupiter, Minerva and Mars. Of course, as St. Augsutine points out in City of God, the deities of the Romans were legion, including gods for door hinges and gods for the stems of plants. But in the Etruscan and early Republican periods, Jupiter, Minerva and Mars were supreme, followed by Vesta, Vertumnus, Janus, Terminus, etc. It is unknown when worship of Jupiter first came to Rome, but it is generally agreed that the cult of Jupiter predates the establishment of the Republic.

Now, next point: Jupiter is itself a compound of two words: Iou and Pater, or "Father Jove," as Jove is the more antiquated name for Jupiter. Jupiter is really Jove.

If we remember our Latin (and Indiana Jones 3: The Last Crusade), we know, of course that the "J" in Latin was not pronounced as the English J, but rather as a kind of Y sound, as in the Latin Iesus ("yay-zoos").

Furthermore, as the classicists remind us, the "V" in classical Latin was not pronounced with a V sound, but had more of a W sound to it. I remember my Latin professor at college pointing out that Caesar's "veni, vidi, vici" would have been pronounced weni, widi, wici. I know that ecclesiastical Latin does not use the classical pronounciation, for which I am extremely grateful; but, as far as I know, there is no debate that the Romans of the Republic used this pronounciation; my understanding is that the debate is about how we ought to pronounce Latin today, not whether or not it was ever pronounced this way in the past. 

Okay, so to put this all together - the Tetragrammaton was pronounced close to the English "Yahweh." If we take the ancient Roman JOVE, which is the real name of Jupiter, and pronounce it how the ancient Romans would have pronounced it (with the J as an I and the V as a W), then we get something that sounds astonishingly similar: IOVE ("Yo-way")...Yahweh ("Yah-way"). Compound this with the fact that Jove was a sky god, which was seen as the dwelling place of the God of Israel (see, for example, 1 Kings 20:23, but also many other places in the Old Testament referring to God's dwelling place as being in the heavens or at the highest places).

So, without getting into a whole complicated theory positing the migration of the Ten Lost Tribes to iron age Italy in the pre-Republican period, could it possible that there was some sort of cultural exchange and that brought the knowledge of the true God into ancient Latium or Etruria? I don't think this is too implausible; and though I am not an expert in the field of etymology, it seems odd that two contemporary peoples could have gods with such similar names without some cultural connection.

Does any of this sound credible or am I drawing lines between points that aren't there?
