Alright, here we go:

• Acquire a miniature breadboard: check
• Cut, drill, and mount another aluminum sheet to serve as additional platform space: check
• Use double-sided tape to mount breadboard and 4-pack double-A battery holder to platform: check
• Rig up wiring from servos to breadboard: check

Voila:

Remaining tasks in the home stretch to walking:

• acquire and rig up a 9V battery holder for powering the micro-controller board
• wire up all the necessary power and data lines to and from the breadboard
• build out from prototype leg-controller code to drive all three leg pairs in concert

We’re almost there.
