Roll offs above the audio band will cause phase shifts within the audio band that are easily measurable. Response two octaves above the audio range can, in some circumstances, minimize this.
Now is the way to go about this letting the existing tweeter roll off causing phase shifts and then adding yet another tweeter and crossover to compensate? I'm not sure.
But then again, some tweeters roll off in the audible band, the Electo-Voice T35 tweeters in my Cornwalls hit the wall at a measured 12K and take the elevator down from there. My apature ribbons, crossed over at 12K add a bit more air to the top end. That said, I ususually don't hassle with them, but that may have more to do with the measured peak in the T35 making it hard to mate with the super tweeters.
