There is a plugin to allpw players yo wear anything as a helmet without commands. I have it in zu online. Buuut i dont remember the name xD im not at home so i cant look for it. Anyway if you use google you will find it :P
Yes it is but a bit buggy yet. We can't know how much time will need xicage to develop a stable release, just be patient or subscribe to help mythicmobs
