Sounds complicated. How would you figure out what it does and how would the enemy AI be able to predict several turns in advance to use it? What happens if you just spam it?
As an example: The ships spam astro-fac for two turns when they use it. I found that simply reacting wasn't enough to block a threat - the gun that made the bullet is still aimed at the ship. But add a load of other blocks and the ship starts tooting it's guns like crazy, just to feed the astro-fac's demands.
I'm probably misinterpreting your idea, but factoring multi-turn events into an AI that's looking after a group of weapons that do different things is a world of nope.
