I think it's possible to recreate a muzzle like that, so that it would look like this from the top view: /O\ but I'm not sure if that would look too different on the back frames.
That's what my model is doing. And that's why it's hard to recreate the speites. When doing /o\, the more back you go, the less appears on the sides. The more you go to the sides, the less/stranger it looks in the front and back.
