WI: Two child policy for Central Asian SSRs.

What would be the effects of the Soviet leadership deciding to impose a two child policy on Azerbaijan, Turkmen, Tajik, Uzbek, and Kyrgyz SSRs sometime arount 1980? From what I read these republics had constant "labor surpluses" that the Soviet leadership had to address and also that these republics were actually some of the more loyal ones staying in the union up until the very end. What would such a move have on the loyalty of these regions and on economic development of the union as a whole? What knock on effects of such policies be on the independent states after SU collapsed?
 
These regions would feel more victimized and thus be more likely to attempt to succeed from Soviet control if such a policy were to be implemented.
 
It could cause a higher percentage of Russians in the region if they are not affected by the policy, but I don't see why the USSR would resort to blatant favouritism and pandering. Of course they could simply turn a blind eye to Russians while actively enforcing it on other ethnic groups, though this is unlikely to mean much as I doubt the policy would be enforced much anyway.
 
It might be more effective to actually get living standards in the SSRs up for the policies to 'work'. The more wealthy and educated Central Asians are, the more family planning takes place and birth rates would drop. Of course, with such a vast domain, it's going to be an even larger drain on Soviet finances. Simple enforcement without such a boost would not have worked outside the cities and even within it. It'll just churn greater resentment.
 
That sort of racially-biased policy would be exceptionally unlikely to be workable in the 1980s Soviet Union. Slavs forcing Muslims to abort or otherwise do away with their children would be a spectacularly bad PR move, particularly at a time when the Soviet Union's credit with the Muslim world (and perhaps, its own Muslim population) was at a low ebb thanks to the invasion of Afghanistan. It might be doable with a more authoritarian and clearly Russian-nationalist Soviet Union, but that would take a significant shift.
 
In dealing with local labour surpluses, a better strategy might have been to promote the migration of workers from these labour-surplus areas to labour-short ones.
