In my mind, if I looked at this setup with its lights off, I would've thought I saw one of the closest to "perfect" PD installs in my few years on the board. Unfortunately, the split single avengers ruined it for me completely. I, too, am not a fan of the lightheads on the liberty interweaved as such on that flash pattern b/c, although it doesn't look too bad at day IMO, I can only imagine what it'll look like at night. I think if they wanted to make that interweaved red/blue look on the Libby work, they would have to slow down and change the flash pattern (Fort Lauderdale PD has lightheads interweaved on their cruisers in the same way, with colored lenses, but it's actually semi-decent looking when the Libby is activated, due to the flash pattern.)
