*First Protestant service performed in Westminster Abbey* when almost everyone else at the time was buried as a Henrician Catholic? And Mary got along fairly well with reformist Catherine Parr...Well, Frances did not have reformist sympathies. Mary was fond of her and she loathed everyone with reformer sympathies. Regardless of the how and why, per Henry 1536 act of Succession (assuming it's not been changed before he dies), Mary and Elizabeth have no claim, nor do any of Margaret Tudor's offspring, so next is Frances.
And who again will be willing to enforce the 1536 Act of Succession? Frances is no more viable a candidate for the throne than Henry Brandon had Henry VIII died in 1533/1534. The Catholics are perfectly satisfied with Mary, and genuine Protestanism, as opposed to Henrician Catholicism(which Cromwell/Cranmer paid lip service to) was very much a fringe sentiment in 1541.
