I am a professional arranger, and my husband is a VERY fine pianist. He also does 2-piano work with our adult son. It will be easier to graft ten more FINGERS onto your hands, than to keep ALL the music in this if you try to cram this into 2 hands.
Have there been things like this done already? Sure - and they are pale compared to the original orchestrations, - or even the 4-hand reductions.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
