Unless you have the interest in HTPC technology, there's not much point in discussing it. Thanks for staying with me on that 'trip though the weeds'. So we've settled on a dual antenna system... For the moment at least.
Yes, your summary of the dual antenna system sounds like you've got the idea. One set of DB8e + Y10713 + preamp aimed at one market, and another antenna array aimed at the other major market is the basic plan.
To use the system without adding the expense and complexity of cable TV head-end hardware, you need to cable a second feed to each TV that will have access to both markets. At each of of the TV's with a dual feed, you need an A/B switch or a second tuner connected to an AUX input or HDMI port.
Trying to mix the output of two UHF antennas or two VHF antennas aimed in different directions generally provides less reliable reception because the two will tend to 'fight' each other. It may be a poor analogy, but imagine two steering wheels, each operated independently, each connected to only one front wheel... Even if the drivers had the same idea of which direction to steer, they would rarely be in exact sync with each other. Tire life and fuel economy would suffer greatly. At a minimum, tuned filters would be needed to make each antenna the favored antenna for only the signals they would be aimed at. When there are lots of signals, you would need lots of filters. Filters are more expensive when they need to have low loss at the desired frequencies and then quickly transition to high loss at nearby frequencies.
