Hello everyone, I'm new to this so bare with me

I'm interested in purchasing a second account (legally of course), but have realized that the only option NCsoft gives is to buy all of the games a second time, in order to recieve an access key.
So my question is, how does one purchase an access key without the unneccessary software (as I have all campaigns)? Say if I were to buy the game of the year edition, would I be able to use existing access keys to allow the characters of my new account to be able to go to all of the campaigns, or do I really have to spend another $60 for a new account? I've asked around a bit, but didn't get a straightfoward answer, and was hoping that someone who has done this from experience could help me out. Thanks in advance
