What if Catherine of Aragon dies of Cancer earlier before Henry VIII tried to divorce her.
It might not be possible to do it that early, as we're shifting it by over a decade earlier. However, shifting things back by a few years should be possible. How about this:
1530: Wolsey dies, Henry is now looking for ways to divorce Catherine without asking the Pope, who is now a de facto prisoner of Charles V (OTL).
1531: OTL: Catherine expelled from her rooms in the Palace. ATL: Catherine falls very ill. Henry is genuinely concerned (not least because he might be suspected of poisoning her). She is not moved from her rooms.
1532: Catherine goes through a period of of serious illness. Occaisionally she is well enough to get out of bed and attend court for a couple of days. Henry, in part out of a desire to maintain the appearance of a benevolent monarch, in part because it's clear that Catherine isn't going to live long anyway and partly because the illness has remined him he still has a few slight feelings for her, makes sure to talk with Catherine during these spells and treat her as Queen. Her health deteriorates throughout the year, however, and in September she finally dies.
1533: Henry marries Anne Boleyn, having left a decent spell between Catherine's death and the marriage (it's still in January however).
Anne's protestant beliefs will still tempt Henry, but without the outright break with Rome it's likely that England will still be Catholic. Henry may end up passing an Edict of Nantes style law though tolerating Protestants.
