Is it possible to implement economic redundancies around a certain system in order to mitigate the sigificance of routes relevant to that specific system and prevent economy balance issues should stations change owners a bit more dynamically than usual (and all this in a reasonably short period of time)?
Everything you said there could be interpreted three different ways. Try again and be more specific. Avoiding one long run-on sentence might help.
What I'm curious about is if it's possible to technically free the economy of a certain system without touching the system itself, but creating redundant copies of anything (equipment, commodity, etc.) unique to it in the surrounding systems instead.
