It is certainly a unique idea, but I don't know if it is focussed enough.
ISTM that the ships fitting that description would be too varied to fit into a single hull size.

A "Derelict" or a "FutureShip" image might be good for scenarios...

I imagine you could just make a Human shipset using variations on saucers and cigar ships, and tell how terran spacetravel was revolutionized by their discovery in the historical description.
