If I'm understanding what you want correctly, using a segment that is "Visits where Page equals (Distinct Count) 1" should do what you want. In other words, Count Distinct should definitely work for pages.
what about to use "Bounces" instead of "Bouncerate"?
A visit that consists of a single server call. For example, a single page visit is a bounce if a visitor does not interact with the page in a way that sends data to Adobe, such as clicking a link or a video start. If more than a single hit is received in a visit, a Bounce is not counted.
