Given that LaTeX is really impossible to reverse once it hits a PDF I doubt that's easy. With some configurations (or LaTeX versions or moon phases, I haven't figured it out) you even get PDFs that contain no text at all because the glyphs don't map to characters anymore. Add into that that each LaTeX PDF contains between 5 and 20 fonts and it gets worse. XeLaTeX makes things much better, but I guess equations are still very much off-limits.
