Option 2 – Could multiple Notch Filters be used to block out the competing signals on each array? The antennas pointing towards Boston/Manchester have filters that block out the signals from Portland and vice-versa for the antennas pointed towards Portland?

More likely it would mostly be a bandpass filter for each desired channel. They would all be combined so that you would only need one coax to each tv without needing an A/B switch. This is the headend (MATV, CATV, or cable) concept that GroundUrMast mentioned.

One of the problems with the A/B method is that each tv has to be able to add a channel after scan, otherwise you would have to rescan after changing to the other antenna. The two tuner method that GroundUrMast mentioned avoids that.
