I'm so sorry, it really sounds like you are in a tough spot. I would probably just go with implants, but I have an impossibly low risk tolerance, so I may not be the best person to ask. Do you think it would also be a good idea to consult with Keller? I'm not sure if he would have anything special to offer; it's just another thought.
I truly wish you the best of luck with whatever you choose to do. I hope you have a nice night, earl25.
