Okay, I've re read the thread now and I think I understand better where you are so I offer the following thoughts. The MCCi is a personal qualification once you have it, no type rating is required, current or otherwise. The ATO employing you would need to have a plan about standardising all their instructors on their training device what ever aircraft type it represents; I assume this is more about operating the device and delivering the syllabus using it. I hope that helps.
