Override the stencil for KeySignature:

\relative c' {
  \once \override Staff.KeySignature #'stencil =
  #(lambda (grob)
     (ly:stencil-combine-at-edge
      (ly:key-signature-interface::print grob)
      Y DOWN
      (grob-interpret-markup grob (markup #:small "A/E"))
       ;; space between keysig and text
      1.5))
  \key a \major
  a1
}
