That has been suggested many times, and I guess it's possible, and I think you'd only need 4 or 5 of the 3' dishes if you phase it right. There seems to be at least two ways to phase them, either by placement, as you say, or by adjusting the length of the feed line between them. I guess I had always thought of using the second way, which always seemed kind of difficult considering the wavelengths involved, but I guess you could do fine adjustments by moving the individual dishes around, closer and further from the sat by fractions of inches. Perhaps you could mount 4 dishes on a track that would allow you to move the dishes forward or back slightly without changing the aim, then you could just nudge each dish a bit along the track to phase them. Seems like this would have to be done separately for each sat though.
A lot of work, but it would be a way to get revenge against some HOA or something.
