Wild. I can read this, no problem, and I can see that it is a clear improvement over standard letters and spelling. Latin letters are (quite literally) a poor match for the English language. They don't match the sounds required to speak English.

I'm not sure if this is a valuable teaching tool, but I think it would be conceptually sound as a general replacement for Latin letters for English text. At this point, though, it's impossible to make such a drastic change. It would have global repercussions.
