Adding power without changing flight path will not work in Airbus FBW as Flare mode is pitching the aircraft down from 30 FT . You will end up hitting the ground harder. On other aircraft there is no defined thrust parameter which will give you consistent flare for you. So you are taking a chance too much will cause ballooning too little hard landing. As far as flare and touchdown is concerned it is flare with elevator and close thrust. You don't add thrust. None of the certification trials have been done with additional thrust. We are talking about a technique that gives you consistent results and not what is possible. It is not impossible to do a good landing from an unstable approach but we don't do it.
