C-GO3 Transforming CGO2+ into CGO3

I doubt it is feasible.
The frame structure/pitch motor configuration is different inside the ball. It would be a challenge just to mechanically hang the CGo3 Camera ball on the CGo2+ frame. Both cameras operate on 5v power, but I suspect the CGo3 demands more current, and I would suspect the 5v power supply of the CGo2+ is not adequate.
The CGo2+ gimbal uses a much less sophisticated gimbal control system. At a minimum, you would need to transpose the CGo2+ IMU to the CGo3. But the CGo3 has more mass. The CGo2+ gimbal is already calibrated to the mass, balance and mechanical resistances of the CGo2+ camera. There would be almost zero hope the hybrid gimbal system would work with a mixture of sensors and electronic components,
