Decreasing the size of systems

[Sturmwind]

So, we all know how there's a certain range to the sun which if you cover, your ship will randomly explode due to you leaving the system. Since I never bothered doing so, I don't exactly know what distance that exactly is, but I just had the pleasure to venture 400 k out.

Now, I don't quite know why a system extends its reach to about 600k in every direction from the sun when about 100k at maximum is being used by the player base, but is there a possibility to decrease that distance to say, 200 or 300k? Having so vast systems is entirely useless and is simply annoying when a trader decides he'll try his chances with infinity instead of paying a tax or a fine.
