I am by no means an expert, but i have seen how the sand bags were "elevated" in a static fashion.

And I know that there is something (my memory doesn't help) I think in Static.ini or Technic.ini, where you can change a number and the object is elevated or sunk on earth (we do have these examples already)

Keep trying, and if success hit you, let me know.
