There's a reason the F-117 is the only airframe that looks like that. It had the aerodynamic efficiency of a brick. The fact is, current airliners have reached a balance of a number of factors resulting in them all looking the same. Ever wonder why the old DC10 style tri-jets went out of favor? Too hard to maintain the tail engine. Concorde? Burned too much fuel, excessively high landing speed/distance (11,800 ft 0_o) because of it's short wings needed for supersonic flight. Why are there no flying wing B-2 style airliners like Popular Science prophetizes about every few years? Nowhere to put windows. Also, tubes lend themselves better to the pressurization cycles that airliners experience. The fact is, it turns out given current market constraints the optimal design is two engines, tube fuselage, narrow swept wings. Style has absolutely no influence over the economics of airline operation.
