my $.02, when faced with the same dilemma (and the exact same GF motivation, though not quite as massive a collection as yours), I opted to ditch my GigE/Mystics. My reasoning, the Sawtooth power LED is green/orange, and it still runs OS 8. No ADC power though...

If it's about consolidating, I'd consider move the Yikes! processor to the B&W (patch the firmware). and the DA... really? That's _so_ the same as a quicksilver... move the logic board to a quicksilver to keep OS 9.1 booting.
