The design does look awesome, just one little thing ... What's with the gimmicky dragon head on the front, seriously? I'm sorry, but it's hard to take the ship seriously like that. It's not freelancer-ish at all.
I also have a tiny little problem with he concept itself. Unless the next step is to create specific mining ships for each house, wouldn't it make things a little ... unfair? Look at it this way: Every house has its freighter, its low level transport and its supertransport. The Hegemon was used universally, so things remained even ship-wise.
Third point: The stats also made raise my eyebrow ... in a bad way. With 2 guns and 7 turrets it has a significant firepower. Now, this would be fine, if not for it's CD. Large cargo plus significant firepower plus Cruise Disrupters makes it the perfect pirating ship. If the ship is restricted to lawful only then it wont be a problem, but if not I can already sense the powerpirates joining the Hogosha/FA by the truckload...
