Updating packs? Can you add lots too?

I love Forgotten Hollow, love the look and feel of the place and the wider neighbourhood, but the part where the houses are located seems like it was dropped there from outer space because there is no connection with the rest of the neighbourhood, just these houses with a park in the middle of nowhere and the only road leads to the cemetery. I was actually thinking of turning Vlad's house into a proper cemetery because it makes no sense to have such a large manor in the middle of a cemetery. I'll probably also make a vampire club under the ground instead.
