Well, in fact they have urgently require to unit, because even after union completed, total GDP would be $240bln which is less than one third of Turkey's alone and it is an energy rich region between Russia and China.
This region was united under the name of Turkestan in the paste. These separate states today are the results of Divide & Rule policies of Russians that favored and encouraged tribal identities. In linguistic stance, Kazakh, Kyrgyz and Tatar languages are from Kipchak branch of Turkish while Turkish, Turkmen, and Azeri Languages are from Oghuz branch. Uzbeks and Uighurs of China speaks something between proto-turkic and oghuz branch. The member of same branches can talk each other without difficulty , inter branch conversations requires some practice.. There is already a huge academic effort under the "common language project" to eliminate the differences between languages.
I think and hope this would be a push for greater union which would include Turkey, Azerbaijan, plus some possible future states. Many existed and projected pipelines , railroad from Turkey till Central Asia (which is under construction), highways (some parts completed, some parts projected) , visa regimes (states are already lifting visa requirments) , military cooperations would be the infrastructure of greater union...

BTW, I also expect another union between United Korea and Japan and maybe Mongolia in middle term..
