I personally don't think anybody should be opening for this. I mean, I think it's safe to say that anybody who's buying a ticket isn't buying it just to see Down. People have been waiting a long time for this have to sit through two bands that they may not even care about? Besides, those extra bands are probably the reason Heaven & Hell had to have their set cut short. So I say drop Down (or drop both bands), and as for Heaven & Hell, get your ass on stage early and give them fans the full show they've been wanting to see.
