The only thing i can point out Qaurto, is I get the impression you ignored the bit about the Bengal pre-dating McAuliffe.
Well, as LOAF points out, the Coral Sea was in service before 2608, while the Bengal was designed in 2619
It's not a matter of canabalistic. It's perfectly reasonable that this ship would share that kind of design characteristic. Also, look at the Exeter. It has the same wing deals, the Gilgamesh is a flying pair of them, the Concordia has them. It's a pretty common Terran design thing.
Well, see, not really - you
are trying to make it a common design trait. The only Terran carrier to feature this kind of wings is the Bengal class. The Concordia features light winglets, while here the so-called wings are really a broadening of the hull, apparently in order to have more place for engines. And as for the Exeter & Gilgamesh, they both have roughly triangular shapes (and so does the Paradigm)... but they are destroyers, not carriers.
...Anyway, all that is moot in light of the revised Coral Sea concept you've presented
. I have to say, I like the new concept much better. I'm glad to hear you'll be adding more engines, though - because if there's one thing that looks un WC-like in this prototype, it's that huge single engine. I like the way you've taken the movie Concodia and carrierised it - IMO, although the movie Concordia is a fairly new design (nearest estimate would be 2630s, based on the Pilgrim war references), it is (along with the Talahassees?) the closest thing we have to a visual representation of pre-McAuliffe battleships... and it seems to me that a heavy carrier from the early 2600s would have probably been a modification of a battleship design (since space carriers were only just coming into being). So, I think the direction you're taking here is a good one.
One suggestion I would have, though, is to take those wall-things on the side of the flight deck (assuming that bit at the front is the flight deck), and extend them into prongs sticking out on the front of the hull.... because unlike those wings from the previous design, forward prongs do seem like a general design feature for Confed carriers
