I'm not an engineer, but I think it would be infeasible for batteries with current battery tech, and have a good range. The Tesla Model S 100kwh battery is about 1300 lbs, and it's a structural member of the car, so removing it is not a quick operation. That's about 25-30% of the weight of the car, just for the battery. The battery essentially is the floor pan. Even an 100 mile battery would still weigh something like 400lbs (plus the weight of the support brackets/frame), and it's hard to put that somewhere in the car where it can easily be swapped, and also not make the car handle poorly.
