I’d leave Moraband as is. I also have nostalgia for KOTOR, but if it comes up again in the new canon it’ll still be Moraband, and that’s no point confusing someone who doesn’t know about the change.
I’m not sure - I think Korriban has more cultural weight even though Moraband has appeared in live action, so if I had to guess, I’d guess it’d reappear as Korriban, not Moraband. That said, it’s easy enough to revert if the canon/culture changes. There have been times before when editors have made a change to best suit interpretation but that they’ve later softened over time - much like with Hal’s more recent prequels which are more forgiving to the original material.
