If you want to do that, the best idea would be to just build a mockup - probably a lot cheaper to convert an old merchant hull to resemble a cruiser from the outside, and you don't have to go into the expenses of getting all the systems working. Let's face it, do you really need the heavy weapons, detection equipment and such on that thing? Sure it'd be cool, but being pragmatic... the moment you try to use them, for whatever reason, you'll probably be sunk by the nearest navy unit that will hopelessly outclass you :p And if you want to be safe from pirates, some small arms would do.
