The Dark Star as a skin for a champion or a champion itself ?

Do you guys think we'll ever see the dark star itself as a skin (maybe ultimate ?) for a champion, or as a champion itself, since it's minions can roam (almost) freely between universes, I'd figure the dark star itself could do the same ?

And yes, I know it's supposed to be the thing corruptants jump into when they're done erasing an entire universe, so it'd technically just be a black hole but all corruptants are monstrosities that can change size and have their shapes altered ( dark star Rhaast for example ), so why not the Dark Star itself ? It could even come out with an event introducing a game mode like odyssey extraction and let us fight it as a final boss, then release it, just like with the Xerath rework.

Your thoughts?
