Practically, I cannot see it happening. Is it a possibility? These are the hurdles.
1. His new marriage would be illicit. He’d have to normalize it. When Protestants convert, their marriage needs no normalization. When Catholics defect in order to get married, however, they have a problem.
2. His holy orders are invalidated by his marriage. Anglican priests accepted into the Catholic Church need to have a valid priesthood. That’s normally rare, since they have to establish apostolic succession through their entire lineage of ordination, with every member in the succession being possibly schismatic, but not apostate. In his case, he, himself, invalidated his orders.
3. He’s excommunicated. He’d have to get absolved by his bishop, at least. I think the Vatican needs to be involved, though, because he was a priest.
4. Should he attempt to repent, and be absolved, and un-excommunicated (?!) and his orders somehow found to be valid, his persistence in his current, married state would make it hard to believe sincerity. He’d probably need to get the marriage annulled.
There are no hurdles for Cutie. He has been excommunicated.
