A/B testing multiple pages

I have a wordpress codebase, where my client wants to run an A/B test, however, it's a test spread out over multiple pages.

What they want to do is remove certain information from 5 different pages on the website, and test that against the same pages, but with that information. This all seems like fun, however:

When a user sees version 1 of a page, said user should also see version 1 of the rest of the pages, and of course this also goes for version 2.

Does anyone have experience with this, and is there perhaps a semi-easy way to set this up?

Thanks
