I'm not familiar with the classification but I know Dreadnought equal to Battleship so it's a bit unfitting since Infinity is a Supercarrier but then again I'm not so sure myself, maybe they have different way in classificating ships.

I hope you would ad the 3 capital ships from Red Alert 3, with a story that they are at each other throats with the ships are forced to separate them,

Why not also add a mirror of USS Enterprise, the Zuikaku from the Imperials. Who would be somewhat of Enterprise's rival in almost anything.

Space Battleship Yamato, rather than having the actual ship come, why not have it that Kancolle Yamato got upgraded by both Halo and StarTrek faeries after she was heavily damaged by Abyssals

What about having Yamato upgraded with her Space Battleship Yamato 2199 kit and Enterprise acquiring her Star Trek kit

Laughing to death: I know this rules all to well
