Going to throw this out there just because: I know that Seeker has an interesting thing with some weapons that cause disruptions and reduce flux dissipation when multiple are in use, so maybe you could do something similar to that if you wanted medium superweapons. Although in my opinion, medium "superweapons" wouldn't really be "super". They would just be strong and, well... Medium. Not big like a "super" weapon seems like it should be, especially considering the type of things that have to be done in vanilla to get weapons to work the way they do based on lore and whatnot. An example would be all the omega weapons. Those large mounts are rather large and that's still cutting edge omega core work, so medium weapons wouldn't make much sense that even compare to those even slightly. (granted even large weapons don't make much sense using the same logic, but it's fine if you just squint a little and mutter "domain tech" a few times...)
On a different note though, I am going to throw out a disclaimer that I am not calling for the weapon to be nerfed or changed in any way because my case is extremely rare and takes a considerable amount of time to replicate without the use of console commands. Anyway, I find that if you take a Conquest and load it down with 6 NovaX cannons with maximum flux dissipation and fire rate hullmods(like from More Hullmods), you can spew so much ordnance at everything in general, even outside your weapon range, nothing can kill you. Frigates never even get close. Even Paragons fall with enough spam. I even took out the Zigg untouched. It simply could not approach. Especially seeing as the shots are also extremely efficient at wiping fighters and missiles. So maybe the only viable Conquest is the one with all NovaX?
