Yes, i tried something like that but as you can see, the  \acciaccatura is 
very far  from the note c''.
It is because the hide note c'' is next to the c'' of  the chord.
So i tried to use :
       \override Staff.NoteCollision #'merge-differently-headed = ##t
but it didn't success because the c'' of the chord is not seen as a 
individual entity.
It exists perhaps a trick to move the acciaccatura to the right (perhaps not 
?), but i think there is a request to do for this problem with grace and 
chords.
The logic would be :
\acciaccatura b'8 {< e' g' c''>4 }   => \acciaccatura b'8  e'
\acciaccatura b'8 {< g'  e ' c''>4 }   => \acciaccatura b'8  g'
\acciaccatura b'8 {< c'' e' g' >4 }   => \acciaccatura b'8  c'' ...
