I would think the missile pods could be done fairly easily, just generate several TEC missile batteries for each battleship. Then after one shot, they could probably be made to blow up. You could have an SDP (see below,) where you simply create/buy more pods.
I'd like to see something like the laser heads implemented if even just graphically.
I have a thread
here regarding Electronic warfare, but the response was fairly luke-warm.
I'd think it'd be fairly easy to set up shrike (all versions), ferrets, SDPs (Super Dreadnoughts, Pods) CLACs (which could already exist as carriers.) A person could also create some of the bigger weapons: Grasers, Grav Lances. Energy Torpedoes and MDMs would be easy if all you want is the greatest range available. But I'm pretty sure this game is not enough of a sim than would truly be required for a faithful translation (duh).
I'm also hoping that there would be some way to eventually figure out a way to bring true missile point-defense to the table.
All of that being said, I would love the opportunity to get involved with a group of people who are willing to bring this about.
