This is not going in Discovery as a separate ship or a replacement for anything...
The design is basic, but freelancer ships are basic. It's not as if the current borderworlds or civvy lines are anything to be drooled over. They serve their purpose; rough and rugged. If anything, this is a step upwards in the fluff factor as far as I'm concerned.
As for Nightfall, I've had that happen once or twice before. It's a strange feeling when somebody makes something you were planning to do. Glad you approve, in any case.
You said Comments were allowed too. Actually I thought I edited my Post. It was laggy at that Time.
Thing is: It really looks like a retarded Sabre. The Nose is too stretched, looks so long and easily breakable. Then, the jump from thick Nose to thin Nose happens too suddenly. Those Wings on the Side could be a thicker too.

If it's going to have the exact same stats as the Sabre we're going to look at some serious balance issues further down the road... Heck, it looks as flat as a Bayonet, but it'll have a VHF powerplant, armor, shielding and guns.
