I'd agree that the cost for 4x fleet ship modules is too damn high.
However, out of the ones mentioned: none.
The B'rel and Guramba have innate abilities not tied to consoles. The devs said they wouldn't make fleet versions of those.
The Orion Marauder... The Guinea pig? (Tell me it doesn't look like this, lol). I think the Corsair was the better choice, visually.
The Kar'fi is feasable, since it's ability is a console. Would be pretty nice.
Myself, I'd gladly buy a Fleet Galaxy with a universal ensign station.
That's what would get my money.
Throw in a 4-3-3 console layout, and I'd be even more willing.
