I think that makes a lot of sense. It seems that less perfect fusions tend to add body parts together rather than "overlapping" them, hence Malachite's four eyes and bizarre placement of limbs. It could also have something to do with the purpose of the fusion: Opal has two eyes because Pearl and Amethyst are single-mindedly focused on their goal of rescuing Steven, plus the eyes are very important for aiming her bow. In Garnet's case, it seems that Ruby takes over most of the motor functions while Sapphire is responsible for tactical thinking and future vision. An extra eye is helpful so that she can use her future vision and regular sight at the same time, but an extra pair of arms would be almost vestigial when she is using her gauntlets.
