Certainly! First of all, instead of adding the span bar engraver to the 
ChoirStaff,
you could just as well use a StaffGroup. To turn these spanned bar lines 
off and
on between different bars, it should work to do
\override ChoirStaff.SpanBar #'transparent = ##f
and
\override ChoirStaff.SpanBar #'transparent = ##f
respectively.
