If Boeing were to give the 737 the 787 treatment the benefit to the flying public, airlines, environment, etc. will be huge but as long as Boeing can sell the 737 without a real upgrade it is a cash cow for them and they'll never stop making it.

The MAX 8 is very literally the 737 being given the 787 treatment. What are you asking for here? 10 abreast seating? Then it would just be a 787...
Carbon fiber could change some of the economics around that, but I'm not sure if the airframes wear out from stress before or after efficiency gains make new planes more desirable.
Not even close. The MAX is as basic a re-engining of the 737 NG as possible. It was an explicit design goal to minimize differences, to the point where pilots don’t even need simulator work to be approved for the MAX. (This was the purpose of the MCAS system that doomed the Lion Air fight, to make the MAX handle as similar as possible to the NG even in almost-stall conditions).
And the 737 NG is itself a refresh of the late-60s 737. Much about the aircraft is unchanged since the 60s: the fuselage cross-section (slightly smaller than the late-80s A320), door arming/opening, lack of RAT, etc.
Much of the cockpit improvements since the 80s (integrated EICAS) are missing from even the MAX, and none of the 787 innovations (composite fuselage, bigger windows, no bleed air/all-electric) were even close to coming to the MAX.
