In that case I suggest a list like

  before-break
  broken-1
  broken-2
  ...
  broken-n

Since this is an optical correction, LilyPond need not care to handle
offsets automatically (well, perhaps vertical shifts for broken ties
with accidentals make sense).  The only important thing is that the
user can reliably recognize which part of the broken spanner he has to
modify.  Again there are LaTeX equivalents: The modification of
various parameters to make pages and paragraphs one line longer or
shorter: \enlargethispage (which expands to \insert) and \looseness.

Sorry, I meant `Replacing the original callback function with
something different'.
