Okay:
I-BBVZ, Z-SSCSm, & F-CVL? (the one converted from the survey cruiser)
Fighters, fighters and more fighters, a handful of PFs to help the fighters, scout channels, adjustable drone loadout for multi-role missions (MIRVs, type IIIs for bombardment, etc.), there's enough here to take out darn near anything...
Oh, wait - this seems to be an exercise in "realistic" ships, not a dream-team-esque kill-them-all fleet...
I-CCZ on the flag, K-D7 and a Hydran HB/Fus CA (their naming is escaping me at the moment) - HB and PPD provide just enough ranged capacity to be a severe threat (nevermind that both ranged weapons are multi-shield and multi-volley for mizia work), plasma/fusion provides close-in deterrence, fighters for PD / "under the radar" strikes, and the Klink as a chaser/dueler/dancer/obliquer/distraction taking advantage of the multi-shield damage output (say CCZ/Hydran attacking from the #1 shield facing, Klink is angling to attack from the #2 or the #6...) Was tempted to use a D5 on the klink, but I prefer the staying power of the true cruisers over the war variants...
