- Use a new wing based upon the 787 wing, but scaled-up.
- Several years later, replace the cabin with a new CFRP design, but continue to use the wing from Phase 1.
Is this even practical?

I think that -ER models will just get the 13ft winglets are speculated and perhaps some engine upgrades. The completely new models, well, perhaps a wing based on the 787, chevrons, an engine output increase. Remember those GE-90-115B's are capable of producing 127,000lbs of thrust, but are only certified for 115,000. LED exterior lighting. Basically, it should be very 787-esque with the massiveness of the 777W.
But I'm really betting that the 777ER will get the winglet retrofit fairly soon.

I believe it is the reverse. For example NZ will have winglets on their trans Tasman A320's but not on the domestic ones.

Winglets? aren't these more efficient for shorter routes? the ER models do ULH. I think raked wingtips are much more optimized for 777-type missions.
