Mmm...It's possible Earth is a combination of Dusts. Fire+Water can make rocks, last time I checked...or was it Lava+Water? Anyway, we could say that here Rock=Earth, or a variation of it.

That way, we could say the basic elements are Fire, Water, Lightning/Energy, and Wind. Ice would be a variation of Water, which you have to admit makes sense. Maybe certain types of Fire Dust+Water Dust can make Earth, or some type of Earth Dust.

Fire and lightning are the closest thing among the basic elements to light, so it would make sense that they combined in a certain way can form "Light". As for how Ice+Wind could form Dark/Death, well people usually feel cold when close to death (Yes, it's a stretch). We could probably change Wind with some other element though.
