I think the implementation details matter a ton here. I bet you can make this thing work and be useful, but you can also follow this blindly and have just an absolute mess.

I worked at a place where a well meaning QA tech rewrote the test suite to use page objects. It was a total mess and I undid most of that work in the end. It just moved a bunch of xpath expressions a long way from the rest of the test code, and it was all single use anyway.
