I'm afraid you have to define a new specific context.
Use the definitions in engraver.ly as a starting point, give
it a special \name and add an \accepts declaration in the
ScoreContext or wherever you want to include your new context.
Examples of adding new contexts can be found in 
input/test/tab-staff.ly and input/test/cue-notes.ly

You could add an offset using
    \property Voice.TupletBracket \set #'extra-offset = #'(0 . 3)
the pair of numbers determine the offset in the horizontal and
vertical directions, respectively.

Take a look at input/regression/molecule-hacking.ly
It can be done, but the result is not perfect.
