Good luck with that...  I am not really sure this is a proper solution:
it allows Voice to be part of a drum staff.  Taking a look at
ly/engraver-init.ly, we see

\context {
  \Staff
  \type "Engraver_group"
  \name "DrumStaff"
  \alias "Staff"

  \remove "Accidental_engraver"
  \remove "Ottava_spanner_engraver"
  \remove "Key_engraver"
  \remove "Piano_pedal_engraver"

  \description "Handles typesetting for percussion."

  \denies "Voice"
  \accepts "DrumVoice"
  \defaultchild "DrumVoice"

  clefGlyph = #"clefs.percussion"
  clefPosition = #0
  \override Script #'staff-padding = #0.75
}

Not having the accidental engraver (as compared to the DrumStaff) is
probably a no-go.  It turns out that being rather blasé about the proper
hierarchy does a more thorough job.  Note that the acceptance of a
recursive drum staff is for the sake of getting a new clef and meter
when resuming in drum mode:
\include "english.ly"

\drums \with { \accepts "Staff" \accepts "DrumStaff" }
{
  ss hh
  \new Voice { \notemode {   \key a\major \clef treble a bf c } }
  \drums { ss hh }
}

Note that accepting Staff means that starting a Voice will call in a
Staff context nested in the DrumStaff implied with \drums.

Like with the previous example, I am somewhat skeptic that this will
work under all important circumstances, but it looks like a somewhat
feasible hack, and at least seems to do a bit more than my first
proposal.
