I don't really see the point in all the variation.
I would axe all the heavy and light frigates, and replace them with a lesser number of Capitol ships of an equal amount of credits.
I would also cut down the fighter force to around 10 mixed of X-Wing/Awing, and pick up the slack with a few more heroes, such as bringing in Han, Red Squadron and Antilles, as we're assuming your number 1 hero choice would be Ackbar.
On top of that, I would reduce the Missile cruisers to 4 at maximum, as any more than that is just wasting credits, since you should not be bringing them in until you have the upper hand in your battle anyway.
So basically, using rough estimation of CapShip to Frigate cost, my fleet would be:
8-10 Mon Cals
1 Ackbar
4 Marauders
1 Millennium Falcon
1 Captain Antilles
12 Vettes/Gunships
10 Fighters (6 Awing, 4 Xwing)
10 Bombers
This fleet is cheaper, and packs more "punch" than Cheapy's, which relies on his Frigates to do much of the fighting, which in the later stages of the game is going to get you killed. For approximately an equal price, his enemy could have fielded 15-20 ISDs, and his fleet would have been decimated by superior firepower, while his fighters and bombers were kept busy by free Ties which at 15-20x2 equals a whole horde of Ties.
