I believe there are open enhancement requests about this. There really should be a way to do it in the case of math. I don't even think it would be that difficult. We have the LaTeX code. We just need a way to say "Display that, instead of the WYSIWYM stuff". Unfortunately, I do not know my way around the math code nearly well enough to do this. Maybe another option would be for us to extend the "external editor" model to math insets. I believe we will soon have the ability to open ERT with an external editor, for cases where the ERT is fairly complex.
