I'll agree with Crayder here. We don't need cutscene skins at all, because we have enough diversification here. Something that the game doesn't have, but in the same time it shouldn't go far from the game's reality. The game isn't about sci-fi, but we do have refferences of zombies and aliens, so those should be on the list.

I would also add some native american skins like this (the costume is the idea, obviously);
Maybe a subdivider skin;
An astronaut skin;

And...I'm out of ideas for the rest of 4. But we don't have to fill them right now.
