If I can chime in here... AFAIK, the Druidic Sorcerer doesn't replace the sorcerer, but changes the druid kit's class to sorcerer via a script. You can still play a regular sorcerer, you only have to use the same HLA table for both regular and "kitted" sorcerers.
The thing is, you'll have to start with a kit under some other class, so you'll end up with some features of the original class.
