you seem to have cut every country up according to linguistic/ethnic groups except afghanistan.
afghanistan would lose much of its western and northern territory as its predominantly persian/tajik/uzbek.
i can understand you adding the pashtun territories of pakistan to that afghanistan in the map but you have added chitral, the northern areas and hazara to - lol!
that map of afghanistan would look very different under your plan you would lose kabul as a capital city as its primarily persian speaking.
