Bringing an empty skill from the eve toon, back into the players cargo hold

I am wondering if there has been talk of being able to take a skill book from the players eve character, and moving it back into the players cargo hold. If not I would like to see an option, that for a fee we would be able to remove say, a Caldari Titan skill book that was injected in the character, and have it back in our paws to sell or transfer to another character. Maybe like $12.98 USA dollars and you can modify the character’s skills that they have in their train ability. I don’t know if this has been brought up, I wouldn’t see why CCP has not thought of this. I guess just waiting for a certain time to do it or something.
