I think we should and some variety to the systems when the interstellar update comes out. Like Rogue Planets, Stars/Planets orbiting Black Holes, Planets orbiting Binary/Trinary Stars, Stars/Planets orbiting Neutron Stars. We could also add events like a Gamma Ray Burst that could hit your vessel or colony, killing some Kerbals. Or, a supernova that could make a system inaccessible for a period of years. Or, a planet/object getting ejected in any direction, this creates a chance for you to be captured and redirected.
