With regard to the optic sugar, you might \usepackage[utf8x]{inputenc}
in connection with some utf-8 special characters, namely let LaTeX cater
for the conversion.

For the input methods of x-symbol, I have no good substitution to
suggest.  It would be a good thing if somebody bothered porting them
over into AUCTeX.  That would require copyright assignments of both
porter and the original X-Symbol author (likely sympathetic to the
endeavor) to have this accepted there.

For the visual component, I consider X-Symbol's approach a bit too
invasive on the buffer text: if things go wrong, you lose original
input.  preview-latex's own way of inserting graphics instead, however,
appears like overkill for the same application space.  A middle ground
would be the use of display properties substituting appropriate Unicode
characters, but not graphics.

The work still has to be done, but once it _has_ been done, chances are
that it will at least be guarded somewhat against bitrot.
