With such a unique set in terms of appearance, there is a very valuable opportunity. Due to the fact that it adds solid costume pieces to a starship along with modifying textures, there is an opportunity to have it grant different appearances depending on the version, like with the Mk XI and XII ground sets.
Perhaps the Mk XII set could look more... complete. Such as - while still asymmetrical - assimilated parts on both nacelles and impulse engines, or more on ships with more nacelles and impulse engines. It could also have a more plated over, pointy metallic appearance, indicating that the ship is being modified by nanoprobes to augment its structure and systems.
