I suspect the Russians may have had some very preliminary conversation with Boeing, and have gotten a little carried away.
Still, here is an aircraft that is useable as-is.
It would probably benefit first from some revised production engineering, to bring build cost down to a level that would allow the aircraft to be offered at a price users would be willing to pay.
Boeing has great presence with engine makers, of course, so something more modern and more efficient should fall readily to hand.
I would love to actually see this deal happen, but then I would love to see the Cleveland Indians win the World Series once during my lifetime.
