I think that would be great. I'd put Battle Chatter in the same place I'd put a Ship Designer, Battle Viewer and Tactical Battles, which I say again, are great ideas BTW, In an RTS/RPG game.
My approach to 4X ie the Role I'm Playing in GalCiv is:
I'm the Evil Overlord. I've just appointed Johnny Bluenose, who had a traumatic childhood and therefore has great anger in him (and a great Resolve stat, too!), as my Minister of Warfare/Galactic Domination, that kind of role... So it's his job to show me the latest, greatest battlecruiser his minions have designed and how it went against the Drengin Laser Fleet 2. It's also his role to determine how best to use that ship in combat and sign-off on any improvements/changes that the battlecruiser might need. As far as I'm concerned, even if Johnny's ship-designing minions are idiots (for listening to his ideas), I'm not going to rock on up to Doofus & Sons Shipbuilders for The Blondini Race Inc and take over their jobs. I'm just going to fire or execute (or maybe both in a swift one-two!) Johnny Bluenose and get someone else in as Minister.
In comparison, I feel it's logical to have a say in what gets researched as that research will effect my Civilization as a whole and I'm not the one spending hours/however long doing the research. Whereas I'm spending hours fiddling with just where the laser should go etc (Or was when I used the Ship Designer in GalCiv2, I guess it's changed in GalCiv4...)
While I'm on a rant, I could compromise: Keep the Ship Designer, bring in the Battle Viewer and maybe even have Tactical Battles but get rid of Jeff!! Wir mussen die Mowlings ausrotten!! I enjoy snarky-funny races, but funny-funny races just don't fit GalCiv for moine (as they say in Australian sport).
