Basically, what I'm saying is, Do the PROJECT champs exist at the same time as Battlecast, Mecha, Full Metal, Hextech, and/or Program champions? cuz it'd be cool if they were all part of the same timeline and actually existed together :D
It seems that the Mecha, the PROJECT and the Battlecast do exist in the same timeline, considering that Mecha Sion has quotes towards them and BC Velkoz appears in the new PROJECT Kat.
Full Metal is likely Jayce's answer to the Battlecast, or a 'good' version hence why Viktor has one. Program looks like it related to Mecha in many ways.
Somehow, I feel Eternum is slightly within the canon, except they're more likely to have void/demonic origin. Maybe even Noxian?
