That might work. For some airlines. If the airline wanted it Boeing would be very happy to deliver.
The airlines re-configure airplanes according to the season.
Some do. Many don't. Again, the decision of where and how to afix row/seat numbers is an airline decision, not a Boeing/Airbus decision. If you have an issue with the decision, take it up with the airline, not the manufacturer.
