Greece and the Megali Idea

I think it would be interesting if Greece, after winning the 4th Balkan war against Bulgaria, could Declare war against the Ottoman Empire when it is at war with the Arab Axis and take the "lost" lands like Constantinople, Eastern Trace and the east coast of the Aegean.

I imagined if Greece gets a Focus tree it should be focused on reconquering the lands that were lost in the Weltkrieg back from the nations that occupy them.
