can lyric spacing be overridden by note spacing?

[Kieren MacMillan]

Hello all!

Just wondering if there's a way to tell Lilypond (2.12 or later) to  
set lyrics with natural *note* spacing, as opposed to natural *lyric*  
spacing...
Here's a snippet showing what I'm hoping to achieve automagically:

\version "2.13"

melody = \relative
{
  c8 d e f g4. f8 | e1
}
words = \lyricmode
{
  On Thanks -- giv -- ing screeched we, “Eek!”
}
\score
{
  \new Staff = "Staff_voice"
  <<
    \new Voice = "Voice_vocal" \melody
    \new Lyrics \lyricsto "Voice_vocal" \words
  >>
}

melodyHacked = \relative
{
  c8-\tweak #'transparent ##t ( d e f) g4. f8 | e1
}
wordsHacked = \lyricmode
{
  \once \override LyricText #'extra-offset = #'(-1 . 0) "On  
Thanksgiving"2
  \override LyricText #'self-alignment-X = #-0.7 screeched we,
  \revert LyricText #'self-alignment-X “Eek!”
}
\score
{
  \new Staff = "Staff_voice"
  <<
    \new Voice = "Voice_vocal" \melodyHacked
    \new Lyrics \lyricsto "Voice_vocal" \wordsHacked
  >>
}

Anyone see a (relatively simple) way to implement such an auto- 
spacing/auto-adjusting feature?
If so, would it be Frog-able (i.e., without me learning C++)?

Thanks,
Kieren.
