I forgot where i've seen it (probably on surrender@20) but they're discussing to make it, just like you said, works like Rengar's unique item they also state that the player can now uppgrade twice his HexCore; (Orange for Yellow + Red; this is the exact example they said about the second uppgrade) .

They didn't meantion what the new passive would look like though ...
