Do away with the current "Iconic Classes" system.
Give players with "Iconic Classes" whatever Iconic "class" they had as an unlocked "race" instead. (such as Warforged or Half-Orc).
Also give these players a new feature called "Iconic Levels".
"Iconic Levels" allows you to start ANY race (that you have unlocked) at level 15, regardless of class, but you have to go to 30 to TR.
Iconic races are now sold individually as just another race, such as "Warforged" or "Half Orc".
For new players, you can now sell them more individual races and a feature called "Iconic Levels", which becomes an uber form of Veteran Status.
