I think that having a fourth thing to go with the Hat, Body, and Aura items would be nice. That fourth thing could be a sort of follower creature like a head fab or a random prop like a can that would float around following the player. I got the idea from remembering about some servers I've been on that had things like it.
I may just be talking nonsense right now because I'm sick but I hope you understand what I'm talking about.
