Do they exist?

I'd really like to use one in my campaign, but I'm not that great at translating stats or making it appropriately powered.

Come to think, I AM using Super Star Destroyer. I wasn't planning on giving it stats, but if anyone has come up with a stat block for it I'd love to hear it!

No Gladiator in the books yet. I've seen some homebrewed before, but not anywhere I can remember; give me a few minutes and I can probably whip something up for you. And there are also no Executor-class stats, but you have the next step down, the Assertor-class, in Lead by Example.

EDIT: Found this, if that fills the need.
