Call me Ishmael

I've had a brain wave!!!! Surely not I hear you say. 
I'm starting to get hooked on Dystopian Wars. I think it's partly due to the Victorian Gentleman within me. That coupled with my love of comic books has given me the above mentioned brain wave.

Allies/Mercenaries!!! So what comes the response!!!

What if your mercenary naval addition happened to be Captain Nemo and the infamous Nautilus? Now that would be extremely cool!!!! This has now led me down an avenue of conundrums. Basically which style of Nautilus do I make?
Do I go for the classic  Harper Goff creation from the original 20,000 leagues film?

This fantastic variation illustrated by Kevin O'Neill? 
(The League of Extrordianry Gentlemen : The Black Dossier)

Or the more modern sleek look from the League of Extraordinary Gentlemen film?

All of these designs are fantastic in their own ways, however I can't decide which would look better on the tabletop with my Prussian fleet. Of course I could build them all and pretend Nemo has a whole fleet of them?!?!? Decisions Decisions.

Would love to know what anyone's views are on this.
