I see ! It seems I was mislead by the Metrosphere picture, which is very much physical and basically encages the star (probably got the mass from somewhere else, the star is too small to provide it without major consequences). A coordinated network of smaller structures scattered around the galaxy definitely sound infinitely more manageable, though still a titanic task that would require immense resources and logistic. Fortunately, the U.R.H ha plenty of both, especially post Kazzack war B)
