Okay, the thing about crossovers is that the Ghost Hunt fandom isn't as big as, say, Harry Potter, or the Avengers. So when you cross Ghost Hunt, or anything that doesn't make the top ten in the browse list, (either for normal stories or crossovers) you don't get a lot of attention for that story, and because of that, fewer people get a chance to read that story. My suggestion? Just post it under one fandom, if it's more grounded in the Ghost Hunt universe, post it under the Ghost Hunt fandom, if it's more grounded in another universe, post it in that fandom. If you're in both, post it twice, under each fandom. Which characters do you spend a lot of time with?
It's hard to find people who have the same interest in you, and so when you have a story idea that hasn't really been done before, fewer people get a chance to read it.
So, take both universe, find out the rules for each, meld them together and have fun with your lovely little story that will grow into something well known. Having the support of other writers and viewers is very important on this site, it keeps a writer going, it encourages them to continue to write their story.
Unless they're known for going on indefinite Hiatus.
