Different cutscenes to future group content based on difficulty levels

For those who raided at the mythic level in WoW, you may have realized that some raids have different cutscenes in, say, normal/heroic vs. mythic. So the story does depend on the difficulty level one is running content in.

For future group content, maybe one should have different cutscenes for, say, SM FPs/ops vs. VM FPs/HM ops vs. MM FPs/NiM ops. In the FP case, also have a different ending based on whether the bonus boss was killed or not, especially if it's unlocked unconditionally.

More expensive to create, sure, but sometimes I'm made to feel, especially when running FPs from 3.0 and older whose bonus bosses are available only in MM, or TfB/SnV (although I have a Dreadful Entity kill, I don't have a Hateful Entity one), that SM may not tell the same story compared to a higher difficulty level.
