Can PagePiling.js and fullPage.js be used together? Honestly, they were not designed with that in mind, but it may be possible. All you need to know in order to integrate them is on the fullpage.js documentation and the pagePiling documentation

However, note this is definitely something not provided out of the box in neither fullPage.js nor pagePiling.js, and support for it is not provided in any form.

It's also worth to know that you can actually emulate pagePiling.js effect with fullPage.js by using it together with the Parallax extension (using offset percentage 100%)

We created this tutorial  tor recreate the Tumblr website where we use the exact same effect that pagePiling.js provides but using fullPage.js. You can check this online demo to see the final result.
