I'm actually going to tweak this a bit - on further thought, it feels like it should require some resources (say, a lot of fuel - consumed, and machinery - not consumed), and probably should not require story points, since being able to do this is not particularly overpowered, to the extend that it should be so limited.
(And, this can only be used when there are no stable points. Adding an extra stable point could in fact be a use that requires a story point; not necessarily because it's overpowered, but because it'd let you break that rule. In any case, though, I don't see letting a system go above 3.)
