Ähm...no. There is no new craftworld ship in BFG Armada II.
You can build the same Wraithships and the same Dragonships (you just have to choose the weapons).
In fact, the Tabletop has more Craftworld ships (50% of the Weaopon Layouts have a Ghostship Variant).
And there are already rules for many Craftworld Ships that are not present in BFG Armada II (Wraithscorpion, Ghosthunter/Warphunter, Specter/Banshee, Naiad, Void Dragon, Phoenix, Stellar Phoenix....).
To your Question: Yes, i have incorporated the Craftworld Ships from BFG Armada II. Before BFG Armada II was released.
All you need for doing this is the "Yriels Raiders" document. If you want even more ships you need the "Add-On Eldar VM EN V2.0" document for everything exept the Phoenix - the Rules for the Phoenix are in Warprift 30.
Edit: For the Corsairs: The Kurnous and the Vaul are from BFG Armada I (but are not present in the Tabletop) - and the Solaris from BFG Armada I+II is the Icarus class from "Book of Nemesis".
I think you can buy models on Shapeways in good Quality (could be more easy than finding ships to use for a conversion).
