It must have been some real junky concrete if it was 6 and broke

the area is not prone to holding lots of water after a rain, I'd
go for it. Rather than sand, I would suggest a compactable select
fill. Here it would be called crusher run or red select. Contact
a local sand and gravel outfit to see what would be normal in your
area. This will still require a thin layer of sand for fine
grading under the pavers.

Let us know how it turns out.

That begs the question- if he adds, say, six inches of
gravel/sand/pavers to the residue of the existing patio, where will that
come up to on the foundation and door openings? Can't say without seeing
it, but I don't see many patios where you can add six inches, unless
there is a step in front of all the doors.
