Is there a way to limit planetary movement? I was hoping for one of the following options:

1) Limit movement to one sector per day or some timing element (not just seconds)
2) Disable movement entirely
3) Increase the Fuel Ore cost of movement substantially
4) Negative ramifications of movement, like unable to use planetary defenses for a day or something
5) Make Planetary thrusters the top upgrade instead of mid upgrade and make it expensive

Basically I want to disable planetary movement or make it a BIG deal to move a planet. All I can find to help is by setting the max citadel level to 3. That wouldn't be so bad if I could combine it with option 5 above, but it would mean people also can't have Shielding or an Interdictor Generator. While that could lead to an interesting game, it's not quite what I'm after.

Any suggestions?
