AHC: Wank Greece

With any POD after Greek independence, wank it so then it AT LEAST has Constantinople, the rest of the Marmara Region, most of the costal parts of the Aegean region, all of Cyprus, and at least a population of 30 million with most people identifying as Greek and being Greek Orthodox. I am using this map for the regions: https://www.google.com/search?q=map...biw=375&bih=635&hl=en-us#imgrc=9F062XyaO1yIQM
What does does it take for Greece to become like this? Do they rename themselves Byzantium? How large is constantinople? Is it the new capital? Or does Athens stay the capital?
 
I actually think that something like this could realistically happen after 1900... the Greco-Turkish War in the 20s would be the central turning point, with a defeat of Mustafa Kemal Pasha being the main POD. While them taking Constantinople is, in my opinion, unrealistic even with a significant Greek victory in that war, they were guaranteed West Thrace following the Great War and the Treaty of Sevres, and were poised to take huge stretches of western Anatolia following the Greco-Turkish War. Cyprus joining could be a simple matter of a referendum later down the line, when the United Kingdom moves toward decolonization. The much, much grimmer part of this however would be the nationalist character of the Hellenic Kingdom ITTL. Ethnic cleansing and expulsion of Turks and Muslims in general is something that would be very likely, and necessary to get the Greek majority (though maybe not, it depends!). Even then, there would still be a sizable Muslim and Turkish minority. If they do take Constantinople it would definitely become a new capital, it's too much of a Symbol to not do that.
 
Constantinople may be named the official capital and the King (Emperor?) may move there, but I doubt the Greek government itself would make the move. Constantinople is way too exposed to foreign attack in order to be a viable capital.
