Right, sorry to kind-of post necro,
But I think that these are spectacular ideas. I've always run mods that increase total available FP so I can get more stuff on without relying on fighting it out with the AI with super-fast skirmishers before I can bring in my destroyers and cruisers without being punished for not capping points. I agree completely that the current capture point system is kind of broken and really doesn't allow any strategy whatsoever, not even on a tactical level, because you're either going to be spread completely over the map and in danger, or pressing the assault up to the top of the battle screen.
I like the idea for increasing battle size and number of possible scenarios, especially the giant asteroids and larger maps - I've always disliked the skirmishing aspect of SS, because it ruins the point of capships. It would also be really cool if you didn't know what benefits a capture point gave until you were close to it - and maybe even make them destroyable!
