Medpore Chin Implant
In my opinion, if you do anything at all, you should have the implant that is already in place sculpted to a more feminine heart shape from anterior. It would be a real struggle to remove the Medpore but it's shape can be changed once it is in place. I've done this with Medpore ear implants with good results.

The projection of the implant is good. The width is not, it is a masculine wide implant. Choice of a better feminine implant with similar projection but tapered central part.
Can be hard to remove
Keeks: Medpor can be hard to remove as it allows tissue ingrowth. After removal, you could have some contour irregularities, and your skin may not stick down to the bone symmetrically. One consideration is to ask your surgeon to trim your existing implant as this may reduce some risk of totally changing it out. If it is made a little less tall and less wide it will probably look quite good. Best of luck. I prefer silicone implants because the edges are a little smoother, they are easier to remove, they are softer, and tend to look more natural.
