Why do you want to do this?

What you want to do is not possible.  Try FontForge, the font editor,
using a FreeType library which has bytecode support enabled.  Then
take a well-hinted TrueType font (say, MS Arial) and debug the
truetype intructions of a glyph.  I believe that you will immediately
see why your suggestion can't work.
