I think you are trying to swim against the stream - instead we should
un-build in the other clefs, by providing a script that allows you to
choose any clef you want, and then runs d-InitialClef "treble" (or
whatever is needed) for treble clef, and so on for the current built-in
clefs.
This way, people can add any other clefs that LilyPond can or will ever
support or ones they add in LilyPond's scheme.
The other way, every time someone wants a new feature they have to find
a C programmer to add it, and unless he's very good you will find
unexpected crashes occurring in distant un-related parts of the program
as memory gets corrupted through incorrect handling of the pointers
(cut, paste, MIDI handling, saving to xml, loading ...). I suspect that
hell will have started to freeze over shortly before it all gets done:-)

I am not seeing this. I notice that if I write this:


MvmntIVoiceI =  {
          a'4 b' c'' d'' \bar "|."
}



        MvmntIVoiceITimeSig = \time 4/4 
MvmntIVoiceIKeySig = { }
 MvmntIVoiceIClef = { }
 
MvmntIVoiceIProlog = { \MvmntIVoiceITimeSig \MvmntIVoiceIKeySig
\MvmntIVoiceIClef}
MvmntIVoiceIMusic =  {\MvmntIVoiceIProlog \MvmntIVoiceI}
MvmntIVoiceIContext =  {\MvmntIVoiceIMusic}
MvmntIStaffI = << { \new DrumStaff                 \MvmntIVoiceIContext
                }
                >>



\score {
<< <<
\MvmntIStaffI

\layout{

}


I get all the notes on the middle line of the staff. I suggest you post
the LilyPond you would like to generate.
