I'd recommend the standard Gothic fleet list for that mix.
I think you have a pretty good mix, if you use some squadronning to keep good ships together. The Dictator and Mars, for example, would both use the same re-load order that way and be able to utilize the higher leadership from one of them for it. The Luanrs and Gothics will work well together as well. Fire batteries, then lances, as they ignore Blast Markers, and your Gothics will finish off whatever the Lunars soften. The Dominator and Overlord should hang back and allow the Dominator's Nova to do it's work, while the big guns on the two ships will scare off anyone hoping to silence the Nova.
Personal opinion, I REALLY like the Emperor for the novice player, the attack craft and bombers provide extra punch, but you already have a nice number of Launch Bays with the Dictator and the Mars. You could use an Oberon, but there I don't know if you can have the standard Gothic list, which is another nicely balanced ship with some launch bays and lances. Or even the grand ol' gunboat herself, the Retribution. With your list, the Retribution could follow her Lunars and Gothics into battle pretty nicely, increasing the length and punch of your line.
