A further thought:
Currently the code will return TextScript not Fingering. Thus we need
to mimic aligning/fontsize like Fingering and loose the possibility to
apply Fingering-overrides/tweaks and fingeringOrientations.

Below a code which will return proper Fingering. It may be called
directly or predefined for certain finger.

\version "2.19.82"

parDoigt =
#(define-event-function (doigt)(ly:music?)
  (if (music-is-of-type? doigt 'fingering-event)
      #{
        -\tweak text
                \markup {
                  \number
                  \concat {
                    \fontsize #-2 "("
                    $(number->string (ly:music-property doigt 'digit))
                    \fontsize #-2 ")"
                  }
                }
        $doigt
      #}
      doigt))


%% predefined using ""
"(1)" = \parDoigt -1
"(2)" = \parDoigt -2
"(3)" = \parDoigt -3
"(4)" = \parDoigt -4
"(5)" = \parDoigt -5

%% predefined using unicode-signs
⑴ = \parDoigt -1

%% predefined using superscript
par¹ = \parDoigt -1


{
  %% direct call
  c''-1\parDoigt -1

  c''-1\"(1)"
  c''-1\"(2)"
  c''-1\"(3)"
  c''-1\"(4)"

  c''-1\par¹

  c''-1\⑴

  \set fingeringOrientations = #'(left)
  <
   c'-1^\"(2)"_\"(1)"
   e'-2^\"(3)"_\"(3)"
   g'-3^\"(4)"_\"(5)"

}
