Possibly, however I suspect it's pretty much unattainable in foreseeable future - it seems to me we might be sort of "stuck" with 2G (maybe except Japan, IIRC one of their main operators managed the feat of pretty much retiring a 2G network, when deploying a 3G one), as a lowest common denominator, with reception pretty much anywhere (so "stuck" because it's not strictly a bad thing).
The usual good enough being the enemy of the better - like we seem to be largely "stuck" with FM radio, CD, or UNIX (which, again, are not necessarily bad things). Even the roll-out of DTV in many places has some... delays.
The real question is: would that be doable on LTE, when using its standard voice transmission protocols?
Anyway, no need for UMTS with AMR-WB codec, and since this one already gives nice quality & you can always set up some data-channel streaming on a smarthpone for more niche usage...
AMR-WB might even get wide deployment sooner than LTE voice.
IMHO you overlook some crucial factors.
First, why do we develop all those new cellular standards? To increase spectral efficiency, of course...
...but then, how do we do it? Well, using more complex radio methods, heavier on the local processing (hence using more energy)
It's about compromises, here how big of a pipe (for simultaneous users!) you want, versus the complexity of the processing that needs to be done by the towers & handsets. The compromise spot of 2G GSM was chosen in very different times - and while, over the last two decades, GSM phones greatly improved in battery life ...remember that initially they were also quite poor at it!
