You can't really. You need TN tech to build ships.
You might be able to go the non-TN race route, but I'm not sure if they'd be able to do anything with the survey ships.
And conventional-<any ship type> is not going to happen
Why ? Conventional engines and conventional missiles
Another modules (TN) - has only on colony fleet ships. New world, new colony, and new research for produce new ships and modules. Old military ships rust without mantainance. Old cargo, geological explorer and colony ships (with conventional engines) can be used in Sol System (but need build refinery for fuel supply).
