I doubt it. Firstly, you will have to provide a method to filter out real movements from intended ones. A sensor on a few muscles may help, but sticking them on your skin every morning would not help towards the goal of "Reasonably good UI".
Secondly, I am not sure one can learn to almost unconsciously think about certain movements of bodily parts. Chances are this will keep requiring too much apof one's attention.
Thirdly, I think temporal resolution will be awful. Even if you can learn to think about say 3 movements simultaneously, I doubt you will get this above a byte per second of bandwidth. Written text is around a bit/character, so that would likely be way below slow speech.
Most of this is opinion/guessing, so feel free to correct things.
