Other (minor) advantages include the usual visual trope (the Pokémon Girafarig comes to mind) that the forward‐facing head is more prominent (the Ram is both bigger than and in front of the Ox), and (super minor, but a nice touch) that the positions of the larger and smaller heads matches that of the original Knight–Camel image (which, incidentally, is used on several (all?) pages featuring the Pushme–Pullyu, not just here)
Would it be worth trying a slightly less flattened Ram? Probably due to the relative roundnesses, it seems to suffer that scaling more than the Ox does
This reasoning seems sound to me
