Wife and I were just talking about the idea a few days ago. Swapping the entire big battery of a car seems like a big ask, and opens up issues of "swapping a brand new battery to an highly used one" etc. What I would rather like is an extendable range in EVs. Sell me a 100KM range car that I will use as-is most of the year. When I go on trips, I'd like to be able to stop the car somewhere, toss it a couple of battery modules (like filling up gas), and that should equip me to drive until next such stop in two or three hours. At the end of my trip, I could simply return the battery modules for a refund of deposit.
