These exist today in the states of Kansas, Minnesota, and S. Dakota ( and perhaps Iowa ). They are called "blender pumps". ( but there's not very many in service yet )
You can choose E10, E20, E30, E50, E85.
The station owner has just two tanks of gas, E10, and E85. The pump does the rest.
Actually, almost every gas station on the planet has blender pumps.
The station owner only buys High Octane and low Octane. The mid-grade is usually a 50/50 mix of the two.
