As others have noted, Tesla tried this with a single station off the I5 and quickly abandoned the idea. The battery is probably the most expensive component in the entire car, and is ultimately a consumable. People would forever be anxious about getting swapped out with a battery with more charge cycles on it than the one they had, ultimately affecting the potential lifespan/resale of the car. Not an insurmountable problem, but a problem that adds a fair deal of complexity to managing the inventory at the charging stations. From what I’ve read, the software on the few Teslas that used this service didn’t understand the battery had been switched at all, and continued measuring battery health as if it was still the same original battery. I certainly wouldn’t have been keen on this idea at all unless the car correctly tracked these things.
