PROJECT, Battlecast, Mecha, and Program: Some Connections?

So I was reading some lore and I thought of some interesting connections between these skin lines.

In the PROJECT universe, PROJECT initiates are fighting against some kind of threat that is not really named. Similarly, the Mecha skinline exists in the same world. Mecha skin chracters were created by Yordles to protect their cities from the same threat.

You can see some Battlecast characters in PROJECT splashart, meaning they exist in that world too. In makes sense that the threat PROJECT and Mecha skins are defending their people from are Viktor's Battlecast creations (also called The Evolution). Mecha Zero Sion was even corrupted by Viktor, making the connection even more prevalent.

Then the Program skins appear to be high-end quantum robots that serve the people at large (Soraka is a healer, Lissandra is some sort of surveillance system, Camille an assassin), but it's unclear who they are aligned with.

In short: PROJECT = Augmented humans to defend against Battlecast monsters [Members: Mecha = Kaiju-like robots designed by Yordles to defend against Battlecast monsters (with Mecha Zero Sion defecting due to Viktor's influence) [Members: Battlecast = aka "The Evolution", creatures created by Creator Viktor to enslave the world and forcibly 'evolve' them. [Members: Program = Civil servant robots with a clear purpose, but it is unclear who they are aligned with [Members:
