It's unlikely they would come up with a sin eaters going through portals boss if the story hadn't been about sin eaters. It's unlikely they would have come up with the entire hades fight if the entire MSQ up until that point hadn't existed.

It's unlikely even the SOS fight would be what it is without the MSQ because the concept of having other warriors comes from the story and the concept of those warriors being the same classes we have access to also comes from the story. Therefore most of the mechanics end up as trying to do black/white mage attacks, ninja attacks, summoner attacks and so on.
