Oh, this is entirely pie-in-the-sky; all luxury and no necessity. As cool as it would be, there are probably more urgent things to do. Funny you should mention Korriban, though; and the part about it being always-or-never: you could use a simple low-chance randomisation roll to decide whether to place a sith assassin or three on the place, or even to choose between different possible spawn configurations. Though that's probably not a priority it might be worth filing as a visual polish thing later- doing it to just one or two specific maps, maybe Byss, Korriban, Eriadu, etcetera, could set the mod off. But not priority at all. Just dreaming aloud at this point, really; it sometimes results in excellent ideas- or wasted time, but that's a fair price to me. I've plenty of time and nought to fill it,
