it's not too late
perhaps EK could modify their order for the next 45+ A380's they have on order and ask for the crew rest to be in the usual position directly behind the cockpit? Since other airlines have it here the engineering issues would be minor, and I wouldn't have thought having a "mixed" fleet would cause any training/SOP issues etc etc......
could finally show the lose face mentality has gone.....
Of course, having crew rest at the far end of the plane does force the flightdeck to mix with the stewardesses and customers, which might be a good thing. The worst thing in customer service is to never go face to face with the people you are serving, think of call centers... totally remote..
