Yeah, those ships are really nice. The only thing I don't like is that they use UEF turrets, which IMO don't fit the design at all (especially their textures). Using the "new" Steve-O's turrets exclusively would've produced a better effect. Returreting the ships in the following way might help:
Large dual turret - Large quad turret from Vexor.
Large single turret - Large dual turret from Hyperion.
Triple flak turret - New triple flak from Vexor.
Dual AA turret - New AA turret from Vexor.
Halberd forward gun - Forward plasma from Hyperion.
Tython forward launcher - Forward launcher from Hyperion.
Dunno about VLSes and button turrets, but the latter could be replaced with dual AAs (MP turrets on angled surfaces had been possible for quite some time). The former could use a reskin at least (new, custom model would be best). I'd throw in some AA missile launchers as well. UEF turrets clash with the rest of textures.
