Dermal Fillers On Top of Chin Implant?

I have a small chin implant that I like, but now wish I had even more projection on the profile than I first wanted when selecting an implant. I do NOT want to have another surgery to replace my current implant (had a difficult and scary recovery the first time), so I'm just wondering if it's okay/safe to have dermal fillers like Radiesse injected on top of the implant to give a little more volume? And if yes, what would you recommend? Thank you!
