The name change is explicitly for changing names from inappropriate to appropriate, not for any RP purpose. Any name change requests like that would get rejected out of hand.
If someone else wants to play an offshoot of your family, they should start their own account and RP it as being an offshoot of your family.
Fundamentally, what you're talking about is, in fact, a new family, so there's no good reason that it should be anything other than that mechanically.
What's the purpose of handing over your account to someone, anyway? Just so that they could start with lots of fame? If they kept your characters, it would cause all kinds of confusion and logical problems, and they would be thrown into the middle of everything at a time when they should be trying to learn the game at their own pace.
It would be useful because they wouldn't have to build up fame to get three characters. Literally one of the worst things for new players in this game is only being able to start in two realms, when there's a total of 6 continents you can start on right away. Finding a realm that's enjoyable thus becomes a matter purely of luck, as it would be frustration to go to one realm, wait a weak to figure out if it's any good, then deleting said character and making a new character in a new realm to try out a new realm. It frankly sucks to be a new player with a new account.
