Looks like this can be simplified as follows.  Cheers, -Paul

\version "2.19.2"

offsetPositions =
\override Slur.positions =
#(lambda (grob)
   (cons
    (cdar (ly:slur::calc-control-points grob))
    (cdar (reverse (ly:slur::calc-control-points grob)))))

\relative c' {
  \offsetPositions
  \once \offset positions #'(5 . 5) Slur
  c'2( c)
  \once \offset positions #'(2 . 2) Slur
  c2( c)
  c2( c)
}
