Olympic -all Vstep will have to do is change the name on the Titanic texture lol, oh and add her Wartime livery too.
Britannic -in her Hospital ship colors and a fantasy regular White Star livery as if she survived the war and re-entered service. Like a new feature if you are sucessful in saving Britannic during the War or any ship from it's "Doomed mission" You have access to its other Liveries. Sounds good to me.
Lusitania -both versions Green stacks with a yellow stripe down the side of the ship and the regular Cunard colors
Mauritania -in Cunard livery, Wartime livery and her White cruise-livery
Teutonic
Oceanic
