This is an interesting idea, first off, and I can see where you're going with it. The thing about reading if someone is in the Character Creator seems iffy. I'm not entirely familiar with a game's general startup, but players, once they enter the game server itself, then people know where they are with the "Find" command, not hard at all. However, if users would like to "Find" another player on Character Creator, that's where it may be tricky.
There would possibly have to be a system introduced where the Creator is shared by users (in this case, friends) to find where you are. Or, alternatively, place a "creator" interface that is already in-game so players do not have to leave at all and edit their characters that way. Alas, I assume the code would be needed for something in that nature.
