Very impressive!
I think that the typical Ordo-soloing Conquest uses double Gauss to improve it's DPS while kiting. Given the Prometheus Mk.II is even better at kiting at some angles, is that something worth trying out?
As far as skills go, as a Civ-grade Hull ship, you don't get any bonuses from Tactical Drills (+5% weapon damage), so with the current loadout, I guess you'd be better off with elite Missile Specialization. Otherwise, if you found an extra 20ish OP for Militarized Subsystems, I think Crew Training completely outperforms Tactical Drills (+15% CR includes a 5% damage boost on top of the other benefits). Or I imagine Damage Control / Point Defense / Field Modulation can be substituted.
