"" is already a valid bar line that has an empty glyph, so just extend 
that one:

%%%%
\version "2.19.82"

\defineBarLine "-span" #'("|" "|" "|")
\layout { \context { \Score defaultBarType = "-span" } }
\new StaffGroup << \new Staff \repeat unfold 12 b'4
                   \new Staff \repeat unfold 12 b'4 >>
%%%%
