Adding new weapons and systems?

[Black_Knyght]

I have a question concerning adding a few new weapons and useful systems to the game.

If I create a new weapon, one that is similar in principal to an existing one ( I.E.: Beam weapon, Ballistic weapon, Missile weapon ), to iI have to create a new family for it, or can I use an existing related one?

The same questions applies for other systems, like Damage Control parties (related to Repair).
