I am sorry, why not to use documented Score.measurePosition?

%------------8<-------------------
partialInline =
 #(define-music-function (parser location nom den mus)
      (integer? integer? ly:music?)
  #{
    \set Score.measurePosition = #(ly:make-moment $nom $den)
    $mus
  #})

\relative c'' {
  c2 c
  \partialInline #-1 #4 { c4 }
  c1
}
%------------8<-------------------

Really sorry, i could miss-n-mess something.
