A dual clutch automatic is really a mechatronic manual. And mechatronic manuals are not very adaptable. They require custom tailored clutch apply and shift algorithms. A good amount of finesse is required to keep those clutches from fragging. With production vehicles, every car is built to the same spec. But as far as transferring the hardware and electronics over to your GTO, it would take about $75K with much of that money going to the custom calibration, not hardware.
