I want someone to retcon the Borg Queen as just another appendage, something along these lines:

If the Collective determines that it wants to open bottles (non-destructively), it creates bottle-opening drones. Similarly, if the Collective determines that it needs a drone with an ego, it creates a Borg Queen. Even if the Queen believes she's in charge, she's just another specialized drone, with no more free will than any other. Perhaps the Borg do this to focus the attention of their [enemies/prey/exploitable natural resources] onto something more humanoid, familiar and relatable- give Starfleet a villain, they'll typically cowboy up instead of trying to think like an alien (notable exception: TOS The Devil In the Dark).

Of course, for the Collective to imagine the need to do this, they'd have to already understand humanoid psychology, which makes for an interesting chicken-and-egg problem
