Kammak, I'd just post to the forum. This question in particular is closer to cutting-edge than newbie, and rarely do people here get annoyed by questions.

I think you're on to the answer to the restrictions. The AI designs and upgrades can ignore some restrictions that apply to humans, but they are also limited in their own ways - for example, as you see, they only design according to the AI design files, so if you do what you already thought of - change the unwanted weapon family to a different number, then they won't use it. That kind of approach (telling the AI specifically what to do) tends to get around such AI issues, and can sometimes be taken advantage of in good/interesting ways.
