I don't have a good solution for you.
In the code I used 'extra-offset (last-resort) at first occurence -
needs to be done in every voice.
Second time I used `\i-really-hope-someone-comes-up-with-something-better'.
The name says it all ...

\versio "2.19.38"

i-really-hope-someone-comes-up-with-something-better =
\once \override Staff.DotColumn.positioning-done =
  #(lambda (grob)
     (ly:grob-set-property! grob 'X-offset 1.3)
     (ly:grob-set-property!
       (ly:grob-array-ref (ly:grob-object grob 'dots) 1)
       'Y-offset -0.5))

\layout {
  \context {
    \Voice
    \consists "Melody_engraver"
    \override Stem #'neutral-direction = #'()
  }
}

global = {
  \key c \major
  \numericTimeSignature
  \time 3/4
}

rightOne = \relative c'' {
  \global
  \new Voice = "soprano" \voiceOne
  \partial 4 g ( | % pickup
  \tweak Dots.extra-offset #'(-1.3 . 0)
  c4.) b8[
  \i-really-hope-someone-comes-up-with-something-better
  c8. d16] | % 1
}

rightTwo = \relative c' {
  \global
 <c e>8._\ff <d f>16 | % pickup
  \stemUp \override NoteColumn.force-hshift = 0.9 g2 g4
  \revert NoteColumn.force-hshift | % 1
}

leftOne = \relative c' {
  \global
   \skip 4 | % pickup
  \change Staff = "right"
  \stemDown
  \tweak Dots.extra-offset #'(-1.3 . -1) e4. d8[ e8. f16] | % 1
}

leftTwo = \relative c' {
  \global
  % Music follows here.
}

pedal = \relative c {
  \global
 \partial 4
  c4 | % pickup
  c4 c c | % 1
 }

\score {
  <<
    \new PianoStaff \with {
      instrumentName = "Org."
      shortInstrumentName = "Org."
    } <<
      \new Staff = "right" << \rightOne \\ \rightTwo >>
      \new Staff = "left" { \clef bass << \leftOne \\ \leftTwo >> }
    >>
    \new Staff = "pedal" { \clef bass \pedal }
  >>
  \layout { }
}
