Can my PEEK chin and jaw implants be replaced? Hoping to achieve a stronger result (photos)

I have PEEK jaw and chin implants but my face is still wonky and jawline and chin weak. Previous double jaw surgery for idiopathic condylar resorption but unhappy with the results as i think too small. Can these be replaced or is it more complex, i have seen better results than i achieved. At my wits end, my jaw as a child was lovely and strong and now i have a double chin and little definition.
