I think the other concern is voter turnout/enthusiasm. The last presidential election had extremely high turnout. Even if voters (in swing states) don’t switch candidates but opt to stay home instead that could translate into a significant electoral problem too.
You do have a point that turn out Is important, but a potential replacement candidate isn’t guaranteed to increase turn out, they could be worse.
And they would only have 4 months to try to fix things, which isn’t a lot of time.
