Large part of this experience comes from having central management that forces all parts to follow same standards, and from investing money into many things that are not essential for smaller stores, but overall contribute to the experience. I believe some sort of shopping platform could be created, but most likely independent stores would need to feel even more pressure to subject itself to stricter rules and more importantly, to understand that better technology equals more sales (or any at all) and that they have to cooperate to continue to exist.
