I did exactly the same. First, please consider that in this snippet 
(without the third voice)

\version "2.11.52"
\paper{ ragged-right=##t }
\new Staff {
<<
% first voice
  {d''2 ~ d''
   d''2 ~ d''}
% second voice in parallel
  {f'2 ~ f'
   \once\override Tie  #'control-points =
   #'((1.5 . -0.5) (2 . 1) (7 . 2) (8 . -1))
   f'2  ~ f'}
> >
}

only the tie in the lower voice is modified, as wanted. What I want to 
engrave is the following:

\version "2.11.52"
\new Staff {
  \key f \major \time 6/8
  <<
    {\relative c'' {
      d4. ~ d4 e8
      d4.( d4) e8}}
    {\relative c' {
      fis4. fis4 a8
      \once\override Tie  #'control-points =
      #'((1.75 . -0.5) (2.5 . 0.75) (8 . 2) (13.5 . -1.2))
      fis4. ~ fis4 a8}}\\
    {\relative c'' {
      a8 a16 a a8 a a a
      a8 a16 a a8 a a a
    }}
  >>
}

In the first bar (the original one) there is a tie-collision, which I can 
solve only changing the tie in the upper voice into a slur (second bar).

Best regards,

Marco
