  This is the conversion I had in my mind.

  When using PS fonts directly in Textures, I think there will be an
encoding problem. At least for math fonts, you could not hope just using
``Helvetica instead of CM''. For text fonts, I know that say the
diacriticals get out of whack, because TeX tries to combine two boxes,
instead of using the single one in the PS font. So you have to get around
this, which I figure relates to the other stuff about kerning diacriticals
discussed here. One can convert PS font metric to TeX font metric, but TeX
can have more glyphs in a font, which allows for more kerning information,
for example.

  I can only refer to Justin's paper, the document
at CTAN. The thing is that there are hundreds of text fonts available, but
only a few, a single digit number, of math fonts available, which in part
depends on the complicated and ad hoc original math font encoding. So, in
part to clear up this difficulty, new math font encodings were suggested.

  So the problem is that it is a lot of work setting it up.
