Not just the personalities affect the fusion, but it's theorized that the closer the relationship between the gems affects the look of the fusion - for example, garnet is much better fused (two arms, two legs) than the deformed Malachite.

What if the relationship between the gems grow stronger over time? Could their fusion look slightly different, like Opal can look a bit altered (especially after Pearl regerated)? Just a thought.
