Okay then, here's what we can probably expect if we roll with the confederacy.
Vulture droids: honestly those are are fairly deadly if rather limited, their discord missles are quite handy and the ability to transform into ground form allows for dynamic assaults and maneuvers, but they are limited by 30 minutes if flight time. A upgrade package is likely required.
Hyena bombers: basically a beefed up vulture with a additional bomber bay for proton torpedos basically a slower but punchier vulture, needs babying.
Tri droid interceptors: spherical death balls, tri droids, are fast, small, nimble and we'll armed, they have sufficient firepower to tear apart any Republic fighter and in some cases are utterly superior to them in some regards, elite interceptors that frankly we should update with shields, turn them into tie defenders on crack.
Munificent class frigates: you now em, you love em, lightly skinned frigates that are know for the overpowered prow torbolaser, during the clone wars it roughly took three munificents to rival and take down a venator star destroyer, however that's due to the venator's massive amount of fighters less so it's fire power. Probably a economic ship that's easy to mass produce and a early workhorse, can doable as a transport and a communications ship due to it's top of the line communications array.
Recusant class light destroyer, the most skeletal and flimsy of cis ships, Recusant are basically guns and nothing else, prow tuebolaser, torbolasers and other assorted weapons fill the ships profiles, probably the most outright cheap and basic ship we could buy since it's capable of being run by a droid brain with barely any crew and is so simple to produce.
Providence class dreadnought: arguably the finest cis ship and a highly modular one to booth, a providence is a well rounded dreadnought/carrier hybrid that likely can take on any combination of pirates or nascent imperial ships if well supported, they also come in bigger variants as a sort of super dreadnought. Highly modular but probably highly expensive in comparison to other ships, quite worth it though.
Lucrehulk class battleship/transport: ah the doughnut of doom! Lucrehulks are 3000 km in diameter monsters that can fit enough droids inside to subjugate a world, it's large size makes it capable of taking a massive amount of punishment and dishing it out in return due to it's high firepower. It can also double as a VERY good transport and relief ship.
Subjugator class heavy cruiser heavy cruiser: frankly I'm not expecting being able to field those monsters, a subjugator carries a ion cannon array that allows it to disable entire fleets with one charge and when supported is basically unassailable, ruiniously expensive but unkillable if we are smart.
Now I would continue but not sure if we would end up with some of the more unknown ships, like the bulwark, the sabaoth or anything else.
