Can I pair 2 pairs of AirPods to MacBook simultaneously?

When FaceTiming, we would like to connect two pairs of AirPods to the MacBook so two people can participating in the FaceTime conversation, periodically drifting in and out of the camera view.

Think about multitasking while FaceTiming with family. At times I will sit infront of the screen while my wife is prepping food. Then she might come over and sit infant of the screen with me. Then I might go make us a drink. All this would work better if we could each pair our AirPods to the FaceTime so we could both hear and talk without sitting right in front of the machine.

We went into the midi settings and created new aggregate devices and selected both our AirPods as one device, but we cannot get the machine to successfully pair to both AirPods.

Any other suggestions?
