I doubt it.  The process interaction performance of Emacs (just
receiving data from a pipe via an output filter and inserting into a
buffer) is awful even when the buffer is not on-screen.  XEmacs is
easily twice as fast, and that is still slow.  preview-latex's
operation was sped up considerably by making its error messages have a
shorter format.
