Complexity and experience is different. Parts of the LHD is like a carrier and others like 071... But not the same together. Every class have their special problems that won't be discovered until real sailors worked on them. They might be able to take learning's from carrier on deck design and 071 learning's for well deck design but a lot of space will have conflict.I think a modern LHD is not as complex as a modern CATOBAR carrier.
I think it would rather go, CATOBAR > STOBAR >> LHD/A > LPD
Say for carriers, below the hanger, you can put all your power generation and storage. But in a LHD you wont have that option because you will need it for the well deck. Or where is the couple hundred marines going to go? Space allocation, and if walking around those new untested spaces is what I'm talking about.
On 016, one of the complaints was the layout is inefficient and not suitable for the sailors needs due to the soviets wanting missiles on ship. So 017 had the whole inside completely redesigned based on feedback. Don't want two LHD without the initial feedback. Unless there is a building somewhere we don't know about that replicates the design (not likely) for sailors to debug.
