Impossible to start with a specific research field for a compatible race & AI . But it's possible to design heavely armored ships by editing the AI DESIGN TYPES file ? (what are "spaces per one" values ???)"

Well, you CAN add racial traits. Otherwise you just have to tell it to research something. The "spaces per one" defines how MANY get put on the ship (so your heavily armored ship). Basiclly, the lower the number of more of that you end up with on the ship.
