I know clearly what you meant. Under 500m, you’re looking at dual 1600mm faction plates, dual faction EANMs, and dual trimarks.
Good luck making it useful for anything, it lacks the fitting space for useful neuts, useful prop mod (10mn won’t cut it with that much mass), and you’ve got just barely enough to fit a meaningful tackle package on.
You’re way better off flying a legion at this point. A “realistic” fit is one you’d be able to use for something.
