I imagine the engines and structure are about as efficient as they can be (for the most part), and while raked wingtips might help a bit, I imagine Boeing or some aftermarket supplier would already have developed them by now if the gains were significant.

Aviation Partners believes the blended winglet is valuable on the original 777 models, but are focusing their R&D on the more lucrative narrowbody jets and 767s, since there are far, far, far more of them out there.
777s are down the list, but they will likely certified a blended winglet at some point in the future if enough customers demand it.
Of all the things to worry about... the Wookie has no pants.
