It may be too soon to tell until we get the whole story, but I would be fine with Historia functioning as its own thing and also double as the default history of the Amazons going forward. It's better than anything that came before (including Marston and Perez), and isn't likely to be topped any time soon, so I don't see a downside.
Only change I might make is having Nubia not be one the original Amazons so she could still be Diana's sister in some capacity.
