Now that is interesting idea. I like it. You schedule an event where even amateur telescope observers can witness in real time, through their own telescope. Simulcast with the video footage of the activation from the moon itself. An equivalent of basically waving the hand to you from the Moon. That would be awesome. Unlikely to happen as I doubt something like that would ever be considered a mission parameter, but it would be pretty cool.
They kinda did just this, though on radio frequencies rather than optical, and somewhat unintentionally.
Radio has two big advantages over optical: you don't have to resolve the source and form an image, you only need to collect enough power. And the background noise level is far lower than at optical frequencies, so a huge antenna was not always needed.
Several radio hams received Apollo signals direct from the moon, and in several ways. Two received S-band signals from Apollo 16 and one (Larry Baysinger) actually received UHF direct from Neil Armstrong's backpack during the Apollo 11 EVA. The funny thing is that the S-band signal was the one designed to go to earth; the UHF signal was only intended to go a few meters from Armstrong to the Lunar Module for relay on the S-band signal! And another funny thing is that had Baysinger tried to receive S-band at that time, he would have failed. This is because the LM transmitter was in FM mode at the time to carry video, and that requires a very large antenna or you get nothing at all (the "capture effect"). Hence the movie "The Dish". (The S-band transmissions could also be made in PM, and that's the mode the other two hams received).
The UHF signal was AM, like aviation, and while it was very noisy you could definitely tell they were there. Using the parameters for Baysinger's equipment I ran the "link budget" myself (I'm both a radio ham and a radio communications R&D engineer) and what I heard is exactly what the budget told me I should hear. The signal even disappeared midway through the EVA when the moon set in Kentucky, and prior to that there was slow fading of the type expected when you get both a direct signal and one reflected from the ground alternately boosting and canceling each other at the antenna. It's a trick often used by radio hams who bounce their own signals off the moon ("moonbounce" or "EME").
But of course all these hams -- private individuals, on their own dime and in their backyards -- were somehow paid off by NASA to keep the secret...
