I have a suggestion you may try: specify a Template File in the Save Options page of the DWG Translator Dialog. In that DWG you should have the text style you want your ARCHICAD font to convert to.
Then, when you specify the Font-style conversion, you can simply select the style from the template file. I have not tried, but that might work.
