Can the mod achieve that ?

Won't be implemented in vanilla:

this would probably require teleporting it, which would be destroy-and-recreate, which in turn would require save all items stored in the hub and rebuilding it.

Not sure that this would be worth the hassle. It might be easier to move stuff around the hub than the hub itself.

So, when the user tries to move the hub, everything else moves in the opposite direction instead? That could work too

Yes, but I am not going to implement that. It is too hard for the value that it provides.
