Any one of us, male or female, has as much "authority" as any male Mormon. All their rituals, ordinations, and endowments are FAKE! Anything you come up with on behalf of your Dad will have just as much effect and power as any made-up Mormon ritual.
I had gotten a legal civil divorce years ago, on the grounds of extreme physical cruelty. In your Dad's case, legal civil marriages end upon one spouse's death, so it's already over.
I was not granted a temple divorce from my ex-husband who beat me many times, strangled me until I stopped beating, and left me with permanent injuries. After trying for 25 years, I quit the cult, and declared my temple marriage "null and void" because my ex had broken the sacred covenants. I also declared myself resigned, and therefore "all temple ordinances were revoked." I declared my children had nothing to do with anything that ever happened in the Mormon temple or Mormon church. Our baptisms were null and void, because we declared them to be so.
I had my own ritualistic temple divorce, in which I repeated the actual temple marriage ceremony, reversing the language, to release me of this terrible burden. My ex-Mormon cousins and I wore temple clothes, mine, my mother's and my aunt's. One cousin was the proxy for my abusive ex. Another cousin was the officiator. The third cousin read an exerpt of a favorite Wordsworth poem, celebrating love and life and nature. I printed up an official-looking "Cancellation of Temple Marriage Sealing" certificate, and forged the signatures of the First Presidency, and we all signed it. Who knows who signs this type of document, or if it's just someone's secretary, or a rubber-stamp signiture.
Besides, the First Presidency has no power or authority from God, in the first place. No Mormon does.
You have the power to create your own vicarious divorce ritual for your Dad, any way you want!
It was a very therapeutic experience for me and my cousins, and my dog, who was the guest, and who helped us eat the pizza, afterwards.
