Speaking of the Russians, a faked moon landing is one of those things that the Soviets would've loved to rub our noses in - if only they had a suspicion that we'd tried to win the Space Race by cheating. They monitored our comms between the spacecraft and Houston carefully, yet, no complaints.
The level of technical wizardry which you attribute to NASA makes one thing plain: it would be cheaper and easier just to go ahead and send up a manned flight.
