Making them swappable would present design challenges, but nothing is impossible if it’s a design requirement. Current EVs distribute batteries wherever they can to distribute the weight and prevent damage from collisions or debris. But if they were required to be a certain form factor and removable, cars would be designed around that. Even better, you could get away with a much shorter range, because most people want higher capacity for the occasional long trip. You might have space for two cells, and only keep one in the car most days.
The problem is that batteries are often deeply integrated for performance reasons. So it’s not so easy to swap them.
