Not only that, you an even modify your neighbors, including their name, model file, how they call you, their personality. Also your town layout, including putting spesific fossil in spesific location, putting spesific painting somewhere, increasing your money to packs, re-arrange weher Tom Nook's is, where the museum is, editing what's in lost and found, changing your Town's name, etc.
In short, you'll be a God of Animal Crossing World, able to modify, create and banish anything in your path
