I personally haven't an issue with you making Aurora a male. I agree with you, I don't think the gender is that big of an issue, but as I said before it seem earlier as if the GM wasn't too sure about it. The reason I am suggesting not combining them because it messes up other people. For example, I was wanting to make a character but due to what is currently available to me it is pretty impossible. The character isn't taken but I am still unable to play it. I just want to avoid that from happening to someone who wants to play one of them. Saying that they are two characters is a complete falsity and doesn't change that you are making it impossible for someone to be one of that characters that you aren't really playing. 

----EDIT-----
Overall, I don't think we should be discussing it. It is only going to cause tension and arguments. I think we should wait until Vicer weighs in since the GM's opinion on CSs is the only opinion that really matters in this case.
