Putting the drivers closer together moves the nulls out further. But the size of the radiators prevents them from being close enough to move the nulls very far. So there is no way to make a horizontal array without having troublesome nulls.
The Beta-8CX might be a relatively close acoustic match. But the one Pi definitely would be, so I've sent plans.
