(Edit: continued reading following comments my apologies.)
So this is pure speculation with speculated specifications (3 cats + 2 elevators)?
No...
The characteristics of 002 (and 075) should definitely be taken seriously, particularly the ones that fzgfzy and pop3 have described in words, such as it being a 70k ton standard displacement conventional CATOBAR carrier, with 3 catapults and 2 elevators...
But that does not mean we should interpret that fzgfzy's sketch of 002 to be what 002 will definitely look like, because a picture provides a significantly greater amount of potential error, ambiguity, and artistic license/error/laziness that may accidentally be interpreted as what something will "definitely" look like.
In other words, only look at his sketches as illustration, but at this stage we cannot interpret his sketches (or anyone's sketches) to describe what it will look like.
So just follow their words instead, rather than their pictures. Just pretend those sketches don't exist.
If it was the Chinese Navy officially providing USN style official depictions of their future projects, then that is a different matter, because obviously those depictions would be expected to be very representative and close to the real thing in many details. But we cannot make anywhere near the same assumption for sketches by anyone not in an official capacity, whether they are big shrimps or otherwise.
Among a few otherss yes.
