After consideration of the above discussion, and being ex-Navy, I believe Nahuris originally meant to design a system ship. Now, there would be no reason why such a ship would need a hyperdrive if it were to be carried in a vehicle bay using the rules for a construction bay. 200 SU per bay for a size 1 hull. IMHO, keep it at size 1, give it a hyperdrive and more drones, and a PDS.
Like this:
Remora class Various Torpedo Corvette (22)
Hull: 1
Engines: 8 7 6 5 4 3 2 1
Shields: 2 1
[a] Torp [2/4/6, 3+, Expendable]
AB, AB, AB, AB, AB, AB
Hyperdrive [O], Point-Defense System [O]
1[H3EQ2a], 2[3ESQ2a], 3[H2ESQ2a], 4[3ES2a], 5[H2ES2a], 6[3EQ2a]
