No, the amount of protrusion is hard-coded for \hbracket.

However, you can create your own markup command and call 
bracketify-stencil yourself:

%%%%
\version "2.19.82"
#(define-markup-command (custom-bracket layout props arg) (markup?)
  #:properties ((thickness 0.1) (protrusion 0.25) (padding 0.1))
  (bracketify-stencil (interpret-markup layout props arg)
    Y thickness protrusion padding))
#(define-markup-command (custom-hbracket layout props arg) (markup?)
  #:properties ((thickness 0.1) (protrusion 0.25) (padding 0.1))
  (bracketify-stencil (interpret-markup layout props arg)
    X thickness protrusion padding))

\markup {
  \hbracket Hello
  \custom-hbracket Hello
  \override #'(thickness . 0.2)
  \override #'(protrusion . 0.5)
  \override #'(padding . 0.3)
  \custom-hbracket Hello

  \bracket Hello
  \custom-bracket Hello
  \override #'(thickness . 0.2)
  \override #'(protrusion . 0.5)
  \override #'(padding . 0.3)
  \custom-bracket Hello
}
%%%%
