Could work it in a way similar to what happens when you decide you want to change gods, you'd incur penalties in relevant experience area's and have to earn those levels back if you want them. No consequences would lead to people just being every class as it is like now, and I'm not positive GK is ready for a system of multiple characters belonging to 1 account since the hoarding + item attainability problems are still out of control.
