Earliest possible period for the Ottoman Empire's disintegration

What would be the earliest possible period for the disintegration of the Ottoman Empire? The Caliphate of Cordoba disintegrated in 1031 which caused many gains for Christian Iberia. Is it possible for that to happen? If the Ottoman Empire disintegrates, would there be a Reconquista-like effect in the Anatolian peninsula? How can an empire be destroyed so early. If it disintegrates, would Anatolia be re-Christianized?
 
A second wind in Crusades (maybe keep a Christian King in the holy land, have a less competent Sejluk leader) could inspire more crusades against up and coming muslim nations, including an infant Ottoman Beyberlik (?).
