Some possibilities:
If Timur's empire survives as a major power long after his death, the Ottomans could be reduced to a vassal state.
If all of Bayezid's sons divide the empire, so that all of them have a kingdom of their own.
Through any combination of civil war, assassination and epidemic, the dynasty goes extinct.
