Crossovers are allowed? Even using terminology from other series like Hogwart, danger beasts, etc. isn't permitted. Although to be fair as long as you change up enough, you can get away with it. For example, my miniserial vampire page is the combination of Twilight and Underworld yet it's allowed because it's not a complete copy of either and it has a original lore with it that doens't contradict canon.

So to a extent maybe, but for the most part you have to change a lot, to the point where it doesn't even look like it came from another series, in order for it to be accepted.
