VAIN macro

i have cosmetic - crown of eternal winter but i dont like the skull animation. i noticed you can reset its global cooldown by equipping a different hat with different mog on it and then re-equipping the crown mog. is there a way to macro that so it loops every 5 seconds on crown and 1 second on different, so i dont have to keep pushing the macro? since all it is is cosmetic and doesnt have on use, seems it should be loopable with a script
