No, there's no need for a special context object,
two Dynamic contexts will do. The key things to
remember are that the flexible spacing variables
act on the space between the context in which they
are applied and the one below, and that Dynamic
contexts are of 'non-staff' type. So you need to
change the nonstaff-nonstaff-spacing variables of
the uppermost Dynamic context. Setting basic-distance
is probably sufficient:
\version "2.19.16"
\score {
<<
\new PianoStaff <<
\new Staff { a' a' a' a' }
\new Staff { \clef bass a a a a }
>>
\new Dynamics
\with {
\override VerticalAxisGroup.nonstaff-nonstaff-spacing.basic-distance = #4
}
{ s\p s s\f s }
\new Dynamics
{ s\sustainOn s s s\sustainOff }
>>
}
If you want to understand this further, the section
to read is
http://www.lilypond.org/doc/v2.19/Documentation/notation/flexible-vertical-spacing-within-systems
and the subsection
