Using dynamics in lyrics

[Peter Chubb]

Hi,
        I'm doing an arrangement of a song, where the different
stanzas in different parts have different dynamics.  I know I can mark
an entire stanza as forte, piano etc., using the trick int he
snippets repository, but how do I do it in the middle of a verse?  
I've tried adding New_dynamic_engraver to the Lyrics context, and that
sort-of works, but the resulting dynamic marks often collide with
the text --- particularly crescendo/diminuendo spanners.

Is there a simple way to do this, or do I have to play with tweaks to
move the dynamic marks around?

Here's an example:

------------------
\version "2.12.0"
vA=\lyrics { \set stanza = #"1. "
 "" \p  \cresc This4 verse gets loud -- er \f \dim then soft -- er \p
}
vB=\lyrics { \set stanza = #"2. "
 "" \p \dim This4 verse gets soft -- er \pp \cresc then loud -- er \f
}

\score {
  << 
    \context Lyrics = vOne \vA
    \context Lyrics = vTwo \vB
  >>
  \layout {
    \context {
      \Lyrics
      \consists "New_dynamic_engraver"
      }
  }
}
