Where do you get these ideas RumourMerchant?
I'd think that Boeing probably have a better idea of how to design a wing than you, unless of course there is something you're not telling us (are you about to roll out a new intercontinental passenger jet from your garden shed?)
Regardless, as the saying goes, if it looks right it'll fly right, and it sure looks right! I'm a little dissapointed they changed the tail from the original concept, but the aircraft as a whole looks great - it reminds me of a glider, which I suppose is the point!
