Wow!  Thanks.  That's some advanced stuff, there.  Hopefully it'll be 
incorporated soon into lilypond itself.

To ensure horizontal alignment throughout, I used the second option.  After 
including the scheme, I used:

\layout {
  \context {
    \Global
    \grobdescriptions #my-grob-descriptions
    #my-event-classes
  }
  \context{
    \RhythmicStaff
    \consists \measureCounterEngraver

      \remove "Time_signature_engraver"
      \remove "Clef_engraver"
      \override BarLine #'transparent = ##t
      \override StaffSymbol #'line-count = #0
  }
}

and also

        \new RhythmicStaff = "MeasureNumbers" {
                \override Staff.MeasureCounter #'font-encoding = #'fetaText
                \override Staff.MeasureCounter #'font-size = #+4
                \measureCounterStart    
                s2.*42
                \measureCounterEnd      
        }
