I don't quite get your point, Pierre. The way I do it works for _all_
PostScript fonts which have the ``standard'' set of 228 glyphs. It
makes no difference if the accented letter has a ``seac'' instruction
in its type1 font program (that's what Adobe refers to as a composite
character, and that's what the CC in the AFM files stands for), if it
uses ``callsubr'' instructions to put the base letter and the accent
together or if it's all done inline in the type1 font program. It's
true that afm2tfm will use the accented letter from the font, if you
put it into the PostScript encoding vector, rather than generating a
VPL composite recipe. The accented letters from the fonts usually
look better (even if they aren't specially designed, especially at
low resolution) than what you can produce with a VPL composite recipe.
So, I can see no reason not to use the accented letters from the font.
But if you for some special reason don't want to do that you can edit
the VPL font by hand (you'll have to do that anyway if you e.g. want
to position the accents differently) or you can use another PostScript
encoding for that font.
