Something like that?
\layout {
\context {
\Staff
\type "Engraver_group"
\name "DynamicsStaff"
\alias "Staff"
\accepts "Dynamics"
\defaultchild "Dynamics"
}
\context {
\PianoStaff
\accepts DynamicsStaff
}
}

Not if it can be avoided: I can’t see any need for such things as
\voiceOne or \stemDown here. Ideally, the VoiceSeparator should just
be ignored so as to avoid such unrequired additional staves to appear.
(I can’t see why anyone would *want* this behavior to happen in a
Dynamics context.)

Indeed. If there was such a thing as a Voice_Separator_Engraver, we
could just \remove it from the Dynamics context, which would be
cleaner. Of course, it may be done the other way around by
\consist-ing a Scheme engraver into the Dynamics context which only
removes VoiceSeparator items. Is it too much of a hack?
Cheers,
Valentin.
