I'm sorry, I didn't ready your email carefully.  That is what I would do
for using PostScript Type 3 fonts.

For PK fonts as produced by MetaFont (which are not PS Type 3), probably
the way to go would be to create a virtual font to achieve the reencoding.
That is the standard way to go in the dvi driver world.

For information on virtual fonts:  use Google.
