Good effort but it looks kinda like a little baby Ulysses Dreadnought with the dual dorsal supports. I have used in games an Oberth class or the Iwo Jima class as a courier or infiltrator.
Listings that I use are>>>
FOC: Fed Oberth Cruiser. Just like the Grissom, a dedicated science ship. These I have named in honor of the Mercury and Apollo astronauts.
FOCC: Fed Oberth Cruiser, Courier (faster speed jump, less weaponry, little in the way of labs, tractors or transporters and low shield output) This not a ship you would want to go into battle on but if you absolutely, positively have to have it overnight. Names I have used are those of famous in the field of journalism. i.e Pulitzer, Koppel, Howard K.Smith, Reasoner, Rooney and my fave Walter Cronkite.
FOC-C: Fed Oberth Cruiser-Commando. 54 leathernecks on a one way trip.
FIW: Fed Iwo Jima Class. Mine are geared toward big contingent(over 60) and low offense high defense. I named them after Bataan Death March survivors and victims.
But gotta say you got style.
