I can't see the value in this. You will pay a LOT of money for your PPL training. Any lesson that doesn't go well is a significant investment possibly wasted.
In an ideal world, all instructors would want the same and teach the same. Reality is, it just isn't like that. Even things that should be identical, one will want 5 kt more on approach than the other, etc.
My advice would be to stick with just the one. If your school can't provide that, find a school that can.
