If you can improve the power/wealth of the Jews within the Ottoman Empire, then I think it'd be possible for a Sultan in a particularly dire position to spin off a tributary state in Palestine under Jewish leadership in exchange for serious financial assistance. Still subservient to the Ottomans(at first), but essentially dominated by a local dynasty, along the lines of other local elites under the Ottomans throughout the Middle East. The extent of autonomy this province would have would vary, but domination of the area by Jews would encourage other Jews to immigrate, strengthening the position of this state vis-a-vis local Muslims and Christians as well as the Ottoman state. This province could break away or secure a large amount of autonomy for itself in the future to the point of being a state within a state, but on the flipside, more influential Jews in positions of power in the OE would likely make them (even more) invested in the survival and prospering of the Empire as IOTL. The problem however, would be getting said Jews that would be able to bankroll the Empire through a particularly bad stretch to want control of Palestine. Simply put, the area wasn't worth all that much, and you need Zionism in order to have Jews invest in the idea of a Jewish state in Palestine. I'd sooner bet on a Jewish suzerain of Salonika or Bursa pre-Zionism than I would Palestine.
