you need a couple of things:
a) a copy of the default Autocad template file called acad.dwt
b) add this to your preferred translator in the Save options (see screenshot)
c) create a font-style conversion table with one item for each font in your file (see 2nd screenshot).
The file I grabbed converts our preferred font to Arial and gets rid of the acad stick font.
