NO, I think adding another part to the WW could be overkill. What we have now are the only things within a close distance of each other, besides the Forbidden Forest, which I actually would like. Anything else would be weird, as nothing else is as close to Hogwarts or Hogsmeade as LC and WW are now. Also, if they come up with a good, plausible explanation for things like The Burrow, Malfoy Manor, Diagon Alley, etc to be that close and it is as good as the current WW, I would be more than fine with WW taking over LC (preferably not Mythos though, nothing should change with that).
