I'd be interested to see this post where an SOE representative said this would never happen. We've allowed it for tradeskill classes for a long time, so I can't rationalize why it wouldn't be considered for adventure classes. If you're willing to completely wipe your progress, spells and everything else associated with your class, I'm not sure why we wouldn't allow it.
The only issue I could see is causing problems for Customer Service because someone does this by "mistake". These are the types of things we would need to work out before we implement this feature.
