Updating a terrain is as simple as rebuilding the static mesh bank, or Poking new vert position values into the old bank.
Like I said though, you'd need to make sure that altering a terrain doesn't cause it to intersect with any rigid bodies, else that collision will be missed.
i.e, you could lower a terrain that a sphere is resting on, but not raise it.
