It's possible that the Ottomans, in the style of Empires since forever, will make rules that encourage Jews to move to the region, and support rulings that allow locals to convert. They weren't a big Muslim conversion machine, they seemed to be happy enough to flip between divide and conquer and relative magnanimity towards their religious populations, like most Empires.
They're unlikely to have a good time.
Thessaloniki was a center of Jewish life for centuries, they had an okay time for most of that, and a golden age for a decent chunk of it. No Nazis, maybe no organized Aaliyah or Zionism, and it could still be majority Jewish today. It's not creating a Jewish version of the Serb-Croat-Bosniak division/connection though.

That was all under Ottoman rule, the conversion of some in the Serb-Croat-Bosniak group to Islam, and the support for Jewish community in Thessaloniki. Something between the two isn't impossible.
