AHC: Turkey becomes a constitutional monarchy

With a POD after 1919, is it feasible for Turkey to become a constitutional monarchy and, how could this occur?

Bonus points for a cadet branch of the House of Osman to become a sultan in a neighbouring country.
 
Well, Ottoman Empire was constitutional monarchy in last century of its existence, and remained so until revolution abolished it completely.

Ataturk experimented with keeping symbolic Caliphate, so it's not inconceivable that he could potentially keep monarchy. I think he was was personal friend with Osman Fuad, so maybe after revolution he could install him as symbolic monarch? Since Osman Fuad was soldier and minor war hero, he could be more palatable to Turkish governing junta.
