This has been treated before (but I forget when on this list) --- you 
can achieve what I think you desire with this definition in your preamble:

%put accent (or whatever) over glyph
\def\overstrike#1#2{\leavevmode
   \setbox0=\hbox{#1}\setbox1=\hbox{#2}\copy0
   \kern -0.5\wd0 \kern -0.5\wd1 \copy1 \kern -0.5\wd1 \kern 0.5\wd0}


And then here's an example in the document:



\overstrike{\d{a}}{¯}



HTH.
