There is two problems here,
1, should the clef look ancient or modern, e.g.
{ \clef "petrucci-f" } or { \clef "bass" }
2, should we exchange a C clef for a G clef
For problem 1 one can look at what theese do
\displayMusic { \clef "petrucci-f" c1 c }
\displayMusic { \clef "bass" c1 c }
(make-music
'SequentialMusic
'elements
(list (make-music
'ContextSpeccedMusic
'context-type
'Staff
'element
(make-music
'SequentialMusic
'elements
(list (make-music
'PropertySet
'value
"clefs.petrucci.f"
'symbol
'clefGlyph)
(make-music
'EventChord
...
(ly:make-pitch -1 0 0))))
(make-music
'EventChord
...
(ly:make-pitch -1 0 0))))))
Where the difference is "clefs.petrucci.f" vs. "clefs.F".
So an \ancientToModernClef should traverce the list and exchange
ancient "clefs.xx" to a modern variant.
=======
Problem two is similar
\displayMusic { \clef "petrucci-c2" c1 c }
\displayMusic { \clef "petrucci-c3" c1 c }
gives this diff
