It's a fine dream to be sure, but the bitterly cynical part of me knows it just will not happen. Superstores have one moral compass, and that is profit. If it increases profit, they will probably consider it. Putting bettas in small containers is cheap and efficient and easy for the customers to carry home, therefore it increases profit. If superstores, which are never really super at all...except perhaps in the fact that they are the largest collection of things of mediocre quality--outside of a packrat's garage sale, were to use anything that holds larger than a pint, they would have to pay more for the containers, water, and time spent cleaning the containers. Customers would have a more difficult time carrying the containers with them, in addition to the store needing to provide more shelf space. Less cheap, less efficient, and less convenient in other words. However! It would be very easy for these stores to change the shape of the containers used such that they are wider than they are tall. I imagine merely doing that would solve many problems associated with superstore bettas.
