With the current interest in MOC contest I wonder if there is a window to canonize the combination models with no story relevance, for example the Kabaya ones, the Inspirational ones (like the Ranama and Kirikori Nui are), the Piraka and Matoran conbiners, etc.
For example as other Dark Hunters, or bulked up Matoran like Gaardus, mutaed beings, etc. With at least as much relevance as Makuta Nui with it’s “a form Terisax used”, just as to acknowledge they existed in canon, not nessesarily as Kaita or related in any way to the characters of the used sets.
