replacing/merging glyphs is tricky ... i remember seeing bugged 
presentations due to this fact (irr very old pdftex was able to do such 
things) for instance because lucida fonts were merged where the names 
were the same but the glyphs actually not (it all depends on where the 
embedded files come from) .. so, a merge would also involve checkign if 
the font programs (subrs for glyphs etc) are the same
