No need to, thanks to the 787.

No, because the 787 Dreamliner is as big as the 767.

No. The basic design is over 40 years old. The 787 now targets the 767 niche but with better fuel economy and longer range. Boeing delivered the last passenger 767 in 2013.
The only reason the 767 assembly line is still alive is to build the KC-46 tankers for the Air Force, plus the six remaining 767-300Fs for FedEx and one for UPS.

Why on Earth would they?
The 767 largest variant, the 400, typically seats 296 passengers in two classes; that is what the 787-9 offers. Boeing has trouble competing with Airbus, why would they compete with themselves on top of it?
