I think the problem is bigger than you think.  If I remember right and I
do consider conodonts every other year when I teach paleontology,
conodonts are not creatures that we know a lot about as biological
enities.  The fossils and assembladges are common and well studied, but
whom they belonged to and exactly what part of the critter they were is
an open question.  I think there are a couple good possibilities of
conodont animal, but what you see as fossils is very little of the
creature (?part around its mouth - one idea).  It is most likely that
they were soft bodied creatures and the conodont elements just a little
part of the chaps.  I don't think you will even find good muscle
attachments on them but now you are getting into technical details that
are out of my area.
