It is possible however the actors would have to work harder. I mean with something like Pokemon it is quite possible compared to really any anime. However it happening I'm not sure about. As actually ever happening. Guess we'll wait and see
I don't think it is though, it's a currently airing anime which is different than those that are already completed. They would have to rush not only the dubbers, translators etc that it takes to even get an episode across the seas, but the original team that works for them in Japan. In short, I don't think it's possible and would do more harm than good.
