This is really for the experts to reply, but most implementations of PS
fonts do not use several of the 256 possible slots, but this would not be
efficient for TeX fonts, which would can use all those slots. In addition,
you can only do kerning for glyph pairs in the same font of 256 glyphs. So
for building a good TeX font, you would have to build a virtual font based
on several PS fonts, adding new kerning information.
But, as Frank Mittelbach pointed out, there is nothing in LaTeX
_requiring_ you to do so.

As Robin Fairbairns pointed out, there is a lot of work involved in
adding full METAFONTness, but you can of course also ignore adding that
In fact there seems to be two wholly different discussion topics going on
The first, which Sebastian Rahtz thinks of, can one take a PS font,
somehow flip it into LaTeX, producing typeset output. This is no problem.
The second question, which I discussed, is how supplying the information
one would normally expect from TeX's full capacity. This takes quite some
effort to add, Robin Fairbairns said.
