I think this thread was around before, but I couldn't find it, the search function being what it is. Anyway, the idea here is to suggest alternate Vice Presidents, such as the title suggests. This isn't meant to be a unified timeline, and the various suggestions and their likely consequences should be discussed individually.
For example, let's start with Gerald Ford. I've heard that Ford considered Bush for the Vice Presidency. What would the result of such an appointment be?
