The game comes out tomorrow. Way too late for any of that stuff to be in the main campaign. Possibly there are some things to think about for an expansion.
Even so, changing the entire skill system is something more suited for another game than an expansion.
I'm not sure what you mean by the camera. It seems to work fine, and they've even recently allowed you to unlock full rotation.
New Elements/Schools are too late, possibly for an expansion.
Larian has vetoed playing as different races, because they don't want to make that just a cosmetic option, and so that would mean writing different reactions for NPC's for all kinds of races. Time, money...
Larian games have never had morality meters unless you count the reputation system, and if I remember right (which I might not be) they aren't that fond of the concept. They tend to prefer to let the player pick what to choose in each circumstance, instead of forcing them to feel like they have to do all one option or all the other.
Those last two things are easier and might be possible in expansions or even mods.
