Mahmud II wanted to get rid of the legacy of Janissaries. And the people hated them as well. I don't give it much chance.
Well yes the people hated them, but the conservative, tampering Janissaries are gone, and I think the Young Turks have a good chance to make this happen because even though these new Janissaries are the top of their class, there is the rest of the military that can counter the Janissaries. And they would choose the most loyal to the Ottoman Empire, and the fittest from those groups. They have history to learn from to fix any mistakes from a new reinstatement of the Jannisarries.
