Long before Artush and Zaur, there was this fascinating (based on description) award winning theatre play by Armenian-American playwright Joyce Van Dyke.

May be they could submit it for the annual HayFest international theatre festival in Yerevan which is known for alternative, thought-provoking plays (to be held on 1-10 October this year).
