mensural black notation

[Alan Fabian]

Hi,

I am doing some excerpt from an edition with Renaissance-music  
notated in mensural black notation. I am using the #'neomensural  
NoteHead style in lilypond, but is there a possibility to make the  
NoteHeads completely black? What I mean with completely black note  
heads you find here:

"black notation"

Thank you,
