Hi Phil & Reinhard,

Reinhard sumarized it well enough: it's not trivial to do.
Also, adding new features to pdftex is not desired now.

If you want to alter the font matrix, maybe it's worthwhile
to take a look at the examples in samplepdf.tex. It requires
some macro programming, but I am sure it's trivial for you.
