Yes, it's possible, if you own the copyright. You can always progress to a less restrictive license, but you can't go the other way. It might end up triggering a lawsuit, though, depending on who thinks they're losing something. CC hasn't been tested very widely in court, yet. Where it has, it has always held up, though. I can't speak to the other stuff.
Is there any reason you chose CC-NC rather than SA?
