Well, I won't answer for him, but the one I'll use for my Mystery helmet is gonna be taller at least. I don't know why they made the DP helmet with such a short RF (except maybe for the box), but even with the smaller helmet, the RF stalk is still not to scale. So, if you get one of those helmets, you'll probably want to make an all new stalk for the RF. it's kinda funny how the DP really looked ok to me until I got my mystery helmet. Now the Dp looks like a deformed dwarf fett helmet.
