Hmmmm, I hope I'm not to late for a suggestion. (and pardon my only passing knowledge of eastern mythology) but there is an benevolent Indian God who is shapped like a an Elephant with a man's head and six arms. Ganish I belive? For a Prime I'd like to reference G-1's shoulder smokestacks. The head splits in three sections: left right middle. The sides contain the ear and tusk, the trunk stays down the middle. The Ganish arms fold across the Ganish torso and the trunk folds down over them. The head halves rotate 180 backwards revealing Primes arms. The legs extend downward forming Prime's legs.
