More automated:

\version "2.16.0"

chordNamesWithRestsLayout =
\with {
        noChordSymbol = #(make-simple-markup "")
        \consists "Rest_engraver"
        \consists "Multi_measure_rest_engraver"
        \override Rest #'font-size = #-4
        \override MultiMeasureRest #'font-size = #-4
        % No idea, why r1 needs to be special-cased:
        \override Rest #'after-line-breaking =
          #(lambda (grob)
            (let* ((dur-log (ly:grob-property grob 'duration-log))
                   (staff-pos (if (= dur-log 0) 0 2)))
            (ly:grob-set-property! grob 'staff-position staff-pos)))
        \override MultiMeasureRest #'staff-position = #2
