Well Gotham already has a superhero in the form of Batman. So i think Kate can go onto Legends for an episode or two and Gotham will still be safe. (At least as much as Gotham City can be)

Personally the Batwoman in this crossover hopefully will be one from the Gotham universe. The one from FOX's TV show Gotham. I know Kate doesn't exist in that world, but maybe they can make it so she does. That way once Batman starts being a thing in that universe, she becomes Batwoman in the crossover right after.
