Just what the title says. What if Henry VII marries Joanna? In OTL the marriage negotiations seemed to be fairly serious and I can't find any specific reasons that the negotiations fell threw. So lets say they marry in either 1505 or 1506 what happens next? Does the marriage produce children and if so is it a daughter, a son or both? If a son, how does having a (much) younger half brother and equally young step mother effect Henry VIII's reign? Is he still obsessed with having a son? Would Henry VIII try to claim Naples on their behalf? Further down the road, would we see a person for the Catholic opposition to rally behind? Or would he be more protestant then his brother?
