I had a sliding genioplasty, maximum projection 10mm, would like further projection. Can I get a 2nd SG for further projection?

I had a sliding genioplasty and my chin was projected 10mm. I would like further projection and I am opposed to a chin implant due to bone erosion/resorption. Considering I’m quite young it’s just not an option, I’m also opposed to frequent use of filler. If the first genioplasty doesn’t preclude a second one for further projection, I think I will go with that. If not I will look into jaw surgery it is just much more expensive . I also have normal occlusion.
