ly:stencil-in-color and ly:stencil-add should help:

%%%%
\version "2.18.2"

tri =
#(let ((coords '((-0.5 0) (0 -1) (0.5 0)))
       (thick 0.1) (scale-x 1) (scale-y 1) (closed? #t)
       (stroke black) (fill white))
  (ly:stencil-add
    (apply ly:stencil-in-color
      (make-connected-path-stencil
        coords thick scale-x scale-y closed? #t)
      fill)
    (apply ly:stencil-in-color
      (make-connected-path-stencil
        coords thick scale-x scale-y closed? #f)
      stroke)))

{
  \override NoteHead.stencil = \tri
  \override NoteHead.stem-attachment = #'(1 . 0.7)
  e'4 f' g' a'
}
