It is a posibilite that arvanites origins was from caucasus area and why not become judaizers like tudela think about vlachs population of greece there are turkish christianity so as
No possibility. Caucasian Albanians probably didn't even speak an Indo-European language, and were not referred to as Albanians by their neighbours (Armenians and Persians), and were assimilated by the modern peoples who inhabit their land (mostly Azeri). They have as much relation to Euro-Albanians as Georgians have to residents of Georgia in the United States. Euro-Albanians are Shqiptars, Caucasian Albanians are something.
But why would you pick a third option when such a third option is automatically destructive? The Khazars got away with it--for a while. I don't buy Albanians, or some segment of them, being Jews to avoid that. Number one, what mass conversions to Judaism were there? Some Arab tribes pre-Islam were Jews, some Berber tribes were reported as being Jews (but other reports show many of them as Christians--maybe a veneer of Christianity, I think it shows they weren't quite converted to any religion or another), some sub-Saharan African groups were Jews, most notably the Beta Israel of Ethiopia. But the conditions that made those people Jews (being on the fringe of the Mediterrean world in that era) does not exist in the time and place of the Arvanites.
Judaism gains nothing, besides a host of antisemitic conspiracy theories at best and at worst, no allies to defend you from whoever wants to invade you.
