Unlike a lot of people, I'm not going for the biggest toys. I prefer to play it smart, thus my private fleet would conists of:
*The XJ7 X-wing Starfighter. Based on the X-wing, the XJ7 features improvements to the weapons and shielding, and was so good it was used by Rogue Squadron during the Second GCW, and considering the first X-wign was good enough to take down an entire moon-sized battlestation, this is my pick for a starfighter.
*The BTL-S8 K-wing Assault Starfighter. As a heavy starfighter/bomber, the K-wing is able to arm itself with 18 different weapons aside from its two laser turrets. Considering its modularity to suit any situation, the K-wing is my pick for a bomber and gunship.
*The Ranger-class Gunship. Based on the Imperials Lancer-class Frigate, which was put to great use by Thrawn, the Ranger is fast for a corvette, and is also armed with enough AA guns to tear shreds through enemy starfighters, so this is my pick for a corvette.
*The ShaShore-class Frigate. Designed to be maneuverable and versatile, the ShaShore may have low armor, but makes up for it with the Mon Calamari's powerful shield designs, and being as versatile as it is as well as speedy, it is my pick for a ship of the line.
*The Venator-class Star Destroyer. As opposed to how most would use the Venator, I would utilize it as a support ship, providing additional fire from afar, but would be primarily used as a carrier, not only transporting the bulk of my starfighters but functioning as a repair ship to damaged fighter-craft, making it ample for my fleet.
*The Imperial II-class Star Destroyer. The heavy hitters of my fleet, the Imperial II-class Star Destroyer was a symbol of power and might to the Empire, and due to its powerful and heavy armament, these things were still considered battlefield titans during the Yuuzhan Vong War, despite being around 40 years old.
*The MC80 Home One-type Star Cruiser. Despite being old and reconverted vessels, the Home Ones were not to be triffled with, as even during the Yuuzhan Vong War these ships served the Mon Calamari Forces in defending their home planet from the invaders, proving how valuable these ships were. In addition to their armament, armor, and heavy shield, there modularity makes them important to me, and thus I would take command of one as my flagship.
I think with a fleet consisting of just these starships I mentioned, I would little trouble dealing with any Imperial Moff with an SSD
