I would think it is no more difficult than deleting the re-supply depot then adding the ability on to the facility you want. I personally wouldn�t give both of them the ability, just the spaceport. SE4 should not have a problem with doing that as it will still meet the call for a re-supply depot and when the game does not find a dedicated facility it will use what ever has the ability.
