You will want to just override the properties of the StaffSymbol, and other
grobs for the vocal staff.

%%%% Here is some test code

#(define Ez_numbers_engraver
   (list
    (cons 'acknowledgers
          (list
           (cons 'note-head-interface
                 (lambda (engraver grob source-engraver)
                   (let* ((context (ly:translator-context engraver))
                          (tonic-pitch (ly:context-property context 'tonic))
                          (tonic-name (ly:pitch-notename tonic-pitch))
                          (grob-pitch
                           (ly:event-property (event-cause grob) 'pitch))
                          (grob-name (ly:pitch-notename grob-pitch))
                          (delta (modulo (- grob-name tonic-name) 7))
                          (note-names
                           (make-vector 7 (number->string (1+ delta)))))
                     (ly:grob-set-property! grob 'note-names
note-names))))))))

\layout {

}

\score {

    \new Staff {
      \override Staff.StaffSymbol #'staff-space = #1.5

%%%%% End of test code

You will find other things that need their size changed as you do more of
the music; you can find out about the properties to change in the Internals
Reference.

c_\ff will put \ff below the note; c^\ff will put it above the note.

Similarly with \markup{Deciso}
