Ah screw it... this is already so full of spoilers, I'm just going to type it out WITH SPOILER WARNING though, just in case.

I don't think either would add anything to the scenes.

Between Macao and Romeo and between Gray and Juvia the "sacrificed for the child" and "sacrificed for the love-interest" are already covered and there would be no need for a second pair of each.

Besides it would suck if either Jellal or Gildarts would go down to fodder-level Gale-Spawns (we already got that with Bacchus -_- ) and the Dragons were busy with the Dragon Slayers, so they aren't really "available" for the killing, unless the person in question is hit by a stray roar. But I don't really see Jellal or Gildarts going down to a single roar, unless it comes from Acnologia.
