Basically you need a tweak not an override to affect single NoteHeads
in a chord.
Though why not have all in one?
\version "2.18.0"
#(define (new-head type)
(lambda (grob)
(let* ((duration (ly:grob-property grob 'duration-log))
(head (format #f "noteheads.d~a~a" duration type))
(stil (ly:font-get-glyph
(ly:grob-default-font grob)
head)))
(if (ly:stencil-empty? stil)
(begin
(ly:warning "Unknown NoteHead: ~a, ignoring." head)
(ly:note-head::print grob))
stil))))
myHead =
#(define-music-function (parser location music)(ly:music?)
(if (music-is-of-type? music 'event-chord)
#{
\override NoteHead.stencil = #(new-head "doThin")
#music
#}
#{
\tweak NoteHead.stencil #(new-head "doThin")
#music
#}))
\relative c' {
\myHead
c2
\myHead
<c e g>4
<
c
\myHead
e
\myHead
\tweak duration-log #1
g
>4
}

Though, Harm's Lilypedia is closed now for every request without
version and tiny, compilable example-code.
