While Santa Claus and his elves are known for their magical abilities and craftsmanship, the addition of "copy atom features" to LEGO Star Wars sets would technically be up to the designers and creators at LEGO. These features could refer to various aspects such as interchangeable parts, modular designs, or unique play functions that enhance the sets' playability.
If you are looking for specific features or enhancements you'd like to see in LEGO Star Wars sets, you might consider sharing your ideas with LEGO through their official channels, as fan feedback can inspire future designs!
