The 5 Darkin Team

Ok so I really love the concept of the Darkin and their story, but we only have 3 of them in the game. So the story goes, there are 5 Darkin left and 3 of them, Varus Rhaast and Aatrox, are already in the game (Although Rhaast is tied to Kayn). These three champions fill up the roles of adc, jungle, and top lane respectively, so I was thinking, since you probably picked the number 5 so you could make a full Darkin team, make the other two unreleased Darkin fill the other two roles of course. Some interesting things I came up with was Varus's sister being a support, but a full tank with cc that heals her and her allies cuz you know blood magic. Then we have the last unknown Darkin who could be a ranged mage in the mid lane to fill the ap damage void and ranged champion void. With this loadout, a DPS top laner, Bruiser jungle, AP mid laner, DPS adc, and Tank/Heal support, the full on Darkin team would work very well together, syncing with the story as they are also an army technically. You could even release the last two Darkin at the same time like Xayah and Rakan were released, and give the two some extra connection seperate from the rest of the Darkin to give the dual release some sense. Anyway I'm excited if you guys ever do this. Anyone else?
