I did read the entire thing. It doesn't mean your "restrictions and limitations" are good.
Your specific battlezones will be conquered by one party, then, following the trend, new battlezones will have to appear to ensure progression since this server still claims to function as a role playing sandbox. The next battlezones will be conquered by the same people and so on, till the entirety of Sirius will belong to one faction. So, the battlezones will only limit the period of time it will take for some to conquer.
Or you plan to stop progression after one conquest? That would make as much sense as stationary planets and trade lanes.
Why I think this is a very bad idea? Because it favors fighting skills and fighting skills only. There's no balance between all the aspects of this mod (trade, diplomacy, fighting, resources).
