I think that you are a better candidate for a genioplasty than a chin implant. With the amount of recession that you exhibit, the chin implant will make your chin appear wider. The genioplasty position is different than the traditional jaw surgery and does not require braces or a hospital...
I would agree with your assessment. The problem with implants is that the shape is not your natural bone shape. Ideally you remove the implant and have a genioplasty which will lead to a more narrow tapered balance.
It appears that you have a short chin and deep mentolabial fold. The chin projection can be reduced and vertically lengthened to provide improved facial balance. The procedure is called a genioplasty and the incision is inside the mouth.
