More ossia help, please

[Phil Holmes]

The code below produces the attached music.  Problem is, I want the ossia 
stave, where the line break occurs, to have a vertical line instead of a 
bracket connecting it to the lower music. I do, however, want the lower 
pieces to have the \ChoirStaff bracket.  Any tips on how I can do this?

\new ChoirStaff
<<
 \new Staff = "Main" {
   \repeat unfold 12 { c'4 }
   <<
     {
       \repeat unfold 12 { c'4 }
       \break
       \repeat unfold 12 { c'4 }
     }
     \new Staff = "OssiaStaff" \with {
       \remove "Time_signature_engraver"
       alignAboveContext = #"Main"
       \override StaffSymbol #'staff-space = #(magstep -3)
       fontSize = #-2
     }
     {
       \repeat unfold 24 { c'4 }
     }
   >>
   \repeat unfold 4 { c'4 }
 }
 \new Staff = "Lower" {
   \repeat unfold 40 { c'4 }
 }
