The only thing that I can think of is to limit carryons to one, and only one, item. That is, no personal item in addition to your carryon. Most of the delays I see in the aisle are because Pax are struggling to maneuver multiple items down the aisle, into the bin, etc. If they have only one item, then they have two hands to manipulate it -- not just one hand with the other dealing with their other item.
This will never happen unless you want major airlines to become budget airlines. The moment a major airlines implements what you are asking, that is when I take my business elsewhere because I greatly value having two carryon items. Personally, I put my backpack under the seat and the roller into the overhead.
