We have a separate area we can house bulls in where they will be in full public view and be able to physically interact with the rest of the herd. The entire habitat is split into four sections- usually one is always closed off for the giraffe feedings by the public. There are two large portions with very obvious gates that are normally open. I'm a bit worried about space but once everyone is friends it should be an issue. There is also talk of getting southern white rhinos in the exhibit, however there are definite plans for a habitat with the same species near where the hippos are going to go. The quarantine will only be thirty days, thankfully. Thousands (maybe millions, can't recall the number) were spent on new off exhibit space for elephants in preparation for this. There is a long trail leading to the barn, lots of improvements, etc.
As for the cows integrating, it should be fine depending on the temper of the new elephants. The current ones are sweeties. Each of the two large portions of the Savannah habitat would be enough for the groups (I.e. Four elephants and all the hoofstock and birds one one side, the rest on the other, and maybe the bull in his area.)
Speaking of the bull, he will be mothered for a while as all the bulls are still pretty young.
