I'm a big fan of all of that stuff. When I go to watch DIF here in Sweden I love all the pre-match chanting, flag displays and flares. However, none of it is organic its all manufactured and choreographed by the Ultras.
From your video you can see the Capos directing the chanting and working the crowd from their special platforms (for the whole match) and next to them the drummers beating out the timing.
I suspect if the club erected platforms in front of the crowd and installed capos and drums there'd be an up roar that this wasn't traditional to the English game.

FWIW I'd try it. It could go brilliantly with Walts Kamikaze-ball approach.
