That would not help if the absolute pitch does not agree with what you
need there.

You didn't bother specifying a \version statement, but the afterGrace
optional argument syntax is 2.19.47, so it seems safe to use 2.19.22
parser/location non-syntax.

\version "2.19.47"

extendedNote =
#(define-music-function (note) (ly:music)
  (make-relative (note) note
  #{ \aftergrace 15/16 $note { \once \hideNotes $note } #}))

At any rate, I was late in the discussion and have no clue what this is
about, but it's quite possible that you want \single \hideNotes rather
than \once \hideNotes here in order to definitely affect only that
single note.
