Nio has some battery swap models that let you drive into a bay and it swaps the battery out for you in 5min or so. That design is likely the only one that would really work with a "change the battery chemistry" option. All other electronic vehicles seem to use the battery ad the base of the car in a sled design, so updating the battery would be a 10k kind of affair, if possible.
