The Ecoliner concept (2 full decks and 2 main engines) cannot be only realised in terms of a twin-aisle aircraft but also in terms of a single-aisle aircraft... The result would be a very interesting product of aviation industry...
Even if you design the Boeing 737-800 which is nearly the longest version of the Boeing 737 with 2 full decks the airplane would be only 40 meters long... That means it was able to land at quite small airports, too - delivering lots of passengers... The double-deck version of the Boeing 737-800 could carry over 300 passengers in a nearly single-class configuration (supposedly the lower deck and the upper deck were the same wide that I don't deem impossible) or 240 passengers and an ice-cream machine... Such a passenger capacity is a crucial expectation from any aircraft that wants to be called an Ecoliner because you want to carry many passengers at the same time instead of many flights of smaller airplanes...
It is also expected from an Ecoliner aircraft to have only 2 engines so that it is maximally fuel-efficient and quiet... It is a big question if a Boeing 737 MAX Ecoliner was able with its 2 CFM LEAP engines and 2 full decks to take-off? I think the Ecoliner concept of Mr. Joe Sutter was capable of high-speed taxiing and of taking-off with 2 entirely normal engines because the Boeing 737-700C (where "C" means Convertible because the airplane can be modified even on a daily basis either to carry 140 passengers or 120 passengers and some cargo or only cargo pallets) is still being produced and it can take off also as a freighter aircraft with its usual engines without any further (it only behaves in the air as a freighter in a different way than the passenger version)...
I guess the Boeing 737 MAX Ecoliner had some excellent flight characteristics once in the air because it is with its 2 full decks nothing but a hot air ballon at cruising altitudes so it would be very fuel-efficient and needed an anchor for landing... Naturally as the Boeing 737 MAX is going to replace the Boeing 737 Next Generation I have only thought of the conversion of the Boeing 737 MAX into a full double-deck Ecoliner marvel with the most modern CFM LEAP engines and the advance technology winglets - even if such an Ecoliner will exceed speed limits that I think should be valid for continental flights in general...
