I you want a 052DL out of 052D you will have to reconstruct the aft part. Otherwise it's not going to work the same way as 052DL. Like I said - not impossible but unlikely. There are simpler solutions to board Z-20 on 052D with minimal hull change, like Icloo suggested.You forget that the 052DL already exists, so it's not like they haven't tested this length already extensively.
Also, you should read up on duck tails, which actually tend to enhance hydrodynamics and improve fuel efficiency. I do believe the Flight IIAs and IIIs have this over the earlier flights, for this exact reason. I think I saw Type 056As also having duck tails.
I think it's reasonable to assume that the 052DL stern addition is a simple (and cost minimal) lengthening of the stern section rather than some kind of massive redesign of the entire stern, especially since there does not seem to be any evidence of a massive redesign in the stern of the 052DL.I you want a 052DL out of 052D you will have to reconstruct the aft part.

Not transom plates; duck tails, more formally stern sponsons. By mentioning duck tail I mean that the Type 056A has it, and the Type 056 does NOT. By duck tail I mean that Flight IIA and III Arleigh Burke has it, and the Flight I/II does not. On the Arleigh Burke these are ~2m deep sections of stern and cover essentially the entirety of the ship's beam, so as far as hydrodynamics is concerned they are not just some tiny inserts. And as I said, these things tend to IMPROVE hydrodynamics and fuel efficiency, not the other way around.By "duck tail" you mean transom plate? Yes, that could also be an option, you are correct that 056 has it.
Older 052D hull though.Another 052DG basking in the sunset, location unknown. Posted by @Tzo-Henci on Weibo.
