If the Diaspora team were willing, I'd love to see assets ported over to Starshatter to make a new BSG mod for that sim. Capship combat is native to SS, after all.
FS-wise, destructible armor subsystems would be pretty cool. You may not have the level of reactive armor and damage control stuff that BP might be able to swing, but this would let you balance what section of the ship was taking fire as well as what weapons would be able to fire. If your forward armor plating was destroyed, you'd take a lot of damage if you make a head-on pass at an enemy ship. Thus, you'd need to make for a broadside attack, where your weapons may not be quite as potent as the forward fixed guns, but at least now you won't be destroyed, etc.
