Replacing physical items with high fidelity video and automating the picking process when the shopper clicks add-to-cart could be sold as an improved experience.

I'd add a physical add-to-cart button with real-time inventory and give shoppers a bracelet when they walk into the store. They can pair that bracelet with their phone. They can either add items digitally from their phone or browse the store and add them from item locations. Stores would transform into customer service/fulfillment locations where storing items on the floor is unnecessary.
