Absolutely not. Breath of the Wild had to play out the way it did. Link had to lose his memories, because he had to choose who he wanted to be as the hero. In the Era of Calamity, he was always told how to get to the next step. His father was a knight, he had the full support of the royal family. In the Era of the Wild, Link reclaimed his past, but he also created his own identity, and that couldn't have happened if he hadn't lost his memories. He could not have defeated Ganon 100 years ago. The Champions had to lose, and I don't want to see any kind of alternate ending. Breath of the Wild already tells a greatly emotionally resonant story, and letting the Champions live would ruin it.
