The problem is not finding a quality tweeter but finding one that will work with the existing crossover. The Scanspeak Revelator is a better tweeter but how it would sound is anyones guess. I remember when I was looking at a pair of these a couple of years ago I noticed that the tweeters were no longer available. Avalon told me then that they were looking for an alternative; did they recommend the ones you bought? Can you have the damaged ones rebuilt? If they don't know of an alternative you are in deep doodoo. Going active might be the only solution if there is no tweeter that can work with the existing crossover.
