Am I the only alone in thinking that gravity wells are too small?

I've seen some posts that say that the GW around planets should be increased to avoid turtling, but I don't think this is good enough. One bad thing about GalCiv was that it was an open galaxy where you could simply fly past everything and just hit someone's planet anytime. The same flaw can be said of Sins because once you are able to jump to other systems, you can simply fly to every system via one star to another. Now I haven't played any of the MoO games but I did play Ascendency and it was sorta similar from what I've seen.

What I want to see is have the GW contain the entire star system with the star in the middle and the planets arrayed around it while the phase lanes are at the outer edges. Since I have no modding skills, I thought I'd put this thought out for others.
