In your situation, I agree that option 2 is for the best.
However, I did have this conversation with my husband, as I didn't have the fear that he might lose his love for me and/or turn me in for apostacy. I told him that my views had changed, why they'd changed and asked how he felt about me being his Power of Attorney for health care. After several discussions, I agreed to honor his wishes (although, as On The Way Out mentioned, I meant it at the time, but I doubt very much that, if the situation actually comes up, I'll be able to carry through with that) and I changed my Advance Directive to state that my daughter would be my alternate power of attorney if my husband was unable or unwilling to serve.
I had been inactive for several years before I broached the topic with him, and it wasn't easy to do, even though I am quite secure in the relationship. I think I would postpone the conversation with your wife until much later.
