The Borg Queen is a compelling specimen: a humanoid brain attached to a mostly robot body. The advantages seem too numerous for them not to have at least contemplated turning every drone into such a creature.
For one thing, the caloric and nutritional needs of the biological component couldn't be more than a couple of Clif bars a day. And if every drone was a weird plug-n-play spine slug then standardized parts could be produced at unprecedentedly huge scale.
So the question becomes: given the success of what I presume is their prototype spine slug drone design, why wouldn't or couldn't the Borg turn every drone into such a creature?
