Hi Phil,
please excuse the late response, I had, and still have, some problems
with my computer.

It's good that you are familiar with plain TeX and TeX primitives.
LaTeX and Context provide convenient user interfaces but these are
only wrappers.  Let's ignore them ATM.

The only way to specify a font in plain TeX is to specify the name of
the .tfm file:


   (means: load cmr10.tfm) 

This means that each real or virtual font needs its own .tfm file.
It's not sufficient to create a new virtual font.  You have to create
a new .tfm file too, otherwise the virtual font won't be accessible.

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
