This is what everyone is already doing, even for relatively small and slow dispensers. It's simply cheaper to have on-site batteries. It makes installation work with a smaller connection to the grid, and makes it possible to install chargers in more places without upgrading the grid connection. Energy arbitrage is profitable on its own, so EV charging stations are almost just an excuse to get some land and a grid connection for more batteries.
