I'm not completely familiar with the PRC tool, however, let me state a few things:
From how it has been described it seems as though this kind of thing runs the risk of creating invalid characters, meaning our servers are configured to enforce legal characters, which are characters that do not have too many attribute points, feats, skill points and so forth. This is a very simple but also effective way of keeping hacked characters off our servers.
Things like subrace attribute bonuses being applied directly to a character rather than to the subrace skin as we do now would throw off the math that Bioware does to make sure things are not outside of where they should be. The same goes for the feats that are added for subraces.
So the PRC character creator is most likely not the best or even a relatively decent option for Layonara.
That said, we have some mechanics in-place for last-minute, self-service character changes that can be done in-game by the player in the Eye of the Storm starting area. This will be available for thr first login of the character and will not be available again for the character ever.
However, things that one will be able to do is to change the character's head, hair and/or skin color, tattoos, deity and other things like setting dynamic appearances for special sub-races like half-giant and goblins.
It won't be able to add things like background feats, because again, there's not really a practical way to do that without making the character illegal.
When this does become available, we'll make an announcement, but this is a system that we have taken from the Vault and are adapting to our purposes.
So um...stay tuned!
