I have very little expertise with LilyPond code, but a look at custos.cc 
shows that it creates a name for a particular glyph as 
"custodes".style.up_or_down.adjustment.  So to use anything other than the 
current styles without changing custos.cc would involve creating new glyphs, 
probably named something like "custodes"."modern"up_or_down.adjustment.  If 
you wanted to use existing glyphs, you would need to change the C code.
