extra-offset is applied _after_ everything including collision
resolution has been run.  So it couldn't possibly help.  Try fudging
around with Y-offset instead.  Possibly using the \offset command.

In ly/propert-init.ly there is

%% text length

textLengthOn = {
  % 0.4 staff-space between adjacent texts
  \override TextScript.extra-spacing-width = #'(-0.0 . 0.4)
  \override TextScript.extra-spacing-height = #'(-inf.0 . +inf.0)
}

textLengthOff = {
  \override TextScript.extra-spacing-width = #'(+inf.0 . -inf.0)
  \override TextScript.extra-spacing-height = #'(0 . 0)
}

and maybe one of those may be adaptable in a useful manner to dynamics?
