@Arrias: Deus Ex......it deals quite heavily with transhumanism. That's not an easy subject to tackle on. And if you sticked solely to augmentations without tackling the subject, then you just get a bunch of Ironwoods walking around.

The main difficulty with crossovers is....well, it depends on the kind of crossover:

1-Character from X ends up in Y fictional work.

2-X work with characters and elements of Y work added in.

Those are just 2 of the most common. With the 1st, there's the problem that different universes have different rules and power levels, which can make writing a story difficult. After all, if Goku from Dragonball, who can easily tear the moon in half with a single kamehameha without even going all out, ended up in Remnant, considering that holding back would be OOC for him, any attempt at a challenge is made null due to his power, or forced since it would be something only he could deal with.

With the 2nd, you need to be faithful to 2+ different works that may have conflicting themes and rules. If you focus too much on 1 work, it barely feels like a crossover. If you, hypothetically, make Deus Ex x RWBY, but the idea is literally just "RWBY with augmentations", then why bother making a crossover? Just make an AU with some Atlesian experiment involving training Cyborg Hunters, you get the exact same thing.
