User blog:AdamGregory03/Fan Made Expansions Articles?

Hi everyone. I'm sure you're all aware of the concept of Expansion Characters. Well, I was wondering one thing. Because I already have some ideas for my own Expansions, I was wondering if the creators of said expansions could make they're own pages for them? Not official pages, ones with the title like:

Or do you think they wouldn't allow that since it may make the Wikia too cluttered? Because if I'm making my own Expansion Characters, and they do get accepted, I'd like people to know about them.
