Unless there's something inherently wrong with 003's design or propulsion I honestly don't see the urgency and rush to make the next one a CVN.
I think 2 CVs is much better suited for PLAN in the forseeabke future as they hone thier skillset operating a full flat deck carrier while also adequately offer practical, power projection goals and availability.
With 4 carriers, PLAN will always have at least one at sea, with the other being able to deploy in a very short amount of time.
I also dont see PLAN carriers home ported in some faraway base. It'll spend most of it's time at sea in the WestPac with the occasional jaunt to Indian ocean, Persian Gulf etc.
.... Then 005 can be like a Ford class CVN.
