Honestly I wonder how much time could be saved on an ultra low cost airline by just permanently locking the above head compartments that people have to stand in the aisle to use. That seems like the biggest hassle. You could even up-charge for above head storage, but only allow seats at the tail of the plane to choose that upgrade. They board first, and they deplane last, ideally holding up no one. This sounds like hell but hey… if it saves a few bucks a seat on a really short flight because they can deplane in 5 minutes… I’d be for it.
