People should definately make superjugs because they're useful and fun and we have waaay too many good cruiser/transport/freighter/corvette models anyways, whereas superjugs are extremely rare and never seen. The superjugs should also be either grey, badly-textured Terran superships or cheap Sathanas rip-offs, the bigger the better. Don't bother actually texturing them, just slap some brown... stuff over them and claim it's the future emissive armour duraplate or something. You should also come up with completely arbitary designations for the ships - for example SSJGDn - and the names should be something that have been used before, because it gives us that warm feeling of familiarity. "Tor" and "Odin" are good, solid Terran names that are not overused.
It's not that easy, though. For your superjugs to be feasible and immersive, you need to implement ridiculously overpowered weaponry into them. One focused beam is usually enough, but it should have firepower to destroy at least Uranus-sized planets with no difficulty whatsoever. If you set up the hitpoints into some insane amount, you can make sure that nobody destroys your superjug - people want to see it, not blow it apart. Your artistic talent must be seen.
And not even that is enough! If you make a superjug - a Shivan one would be ingenious - you should make it's Terran counterpart at least 2 kilometers bigger [although that's a bit too little in my opinion], and the Terran ship must have a cool name as well. AND HUGE ÜBERBEAM.
