I wonder if a mechanical solution could be used: fold away the arm rests and squash the seats together. 6 armrests folded away would make the isle twice as wide. This could make boarding and exiting more than twice as fast because you have double the capacity and people can overtake others stowing luggage.
Interesting engineering challenge to design those seats. Perhaps leave the armrests and use a wormwheel to make the seats narrower is easier to implement. Could be hilarious if engaged while people are sitting in them.
