Okay, I've actually had a proper think now.
What i'd do is make a High Tech ship that uses an array of artificial gravity generators around the pilot to lower/remove the effects of G on the pilot.
So far we have G-Safe which limits the ships turn and acceleration to keep the pilot from blackout/redout, but this is crap: High performance ships are gimped by G-Safe bringing them down to the level of less powerful craft just because the pilot is the weak point in the vehicle.
So Anti-G would use Artificial Gravity to remove the problem. Why pander to the symptoms when you can cure the problem with the application of science already available in game?
So the design Pros: The cockpit would be in the ship body as a whole so the Anti-G array can surround the pilot. (Think 300 series vs a Buccaneer where the cockpit sticks out). The materials the ship is made of will have to be light but strong, as the Anti-G system would pull on the ship from the inside out, this also means the design itself would have to take this into account to be strong in very different ways, giving it a look unlike any other ship available. Finally the engines would be very big for all that glorious speed and the Mav Thrusters all over to give the ship the maneuverability the Anti-G system was made for. Multiple generators would power all of this fresh madness!
The design Cons: There would not be much spare power left over for shields and weapons. Once the Anti-G is damaged and knocked out, the ships biggest strength becomes its greatest weakness as it would easily KO or even kill a pilot not flying it very gently after Anti-G went off-line. Although the light materials are light and very strong, that doesn't mean they are heavily armored. Power constraints mean smaller/fewer hardpoints for guns than other ships in its size and class, close range Neutron weapons would be its specialty and most deadly loadout, lighter shields than those in its size and class with the crafts speed and maneuverability being its armor and countermeasures. If you aren't moving fast in this ship you are a sitting duck but if it gets behind an anemy ship it'll stick to it like glue.
Thats the potential I see in the 300 series, thats how i'd design a ship from the inside out. Reworks comin', fingers crossed!
