Well... maybe not a very bad idea to bring the realism more into the game, but in the end it might cause the ppl leave this mod when you will limit the freedom of choice for them.
Realism isnt always a good decision, still FL Disco is more like arcade style game miles away from what we can call a realistic space sim, imagine another thing - the dynamic economy proposition, many ppl were screaming for that last years, FL Crossfire runs it already... there are 20 - 30 players online in the prime time evenings to play it... i want to say that, every thing that will limit the actual players will do damage to the community in a bigger way as it is now with capspam.
