Why not have a 3rd variation of the twin-cannon mass-missile shatterbot on here? This, being what I play in QP, definitely drifts away from the S7 versions in cooling, because in a normal brawl using just the MRM and LBXs is plenty cool. ERSLs are for if you run out of ammo (it's happened to me, dry on LBX ammo) or to draw a dick and balls in the ground. And it has 2 JJs. They're super ultra useful, and are definitely not installed for the sole reason of mocking any lesser Banshee's you drop with. Also recommended pattern colors are Red Green Yellow because it makes it look like a Taco Time uniform from the 80's.
My take on this build: Essentially I'm trading some sustained DPS and cooling for more Alpha with the 4 Meds. I also like to think 4 meds scares lights more than 2 ERSMLs. As slow as this build is, I don't want to encourage a war of attrition with a MCG light. I also switched up the ammo ratio to favor the LB10Xs. This guy plays a lot like my Legend-Killer now, which I personally enjoy. I like to plug away with the LB10Xs. I find a lot of enemy pilots under estimate their cool-down and try to brawl when they shouldn't. Unfortunately the JJs had to go, so you'll have to style on the other Banshees by breaking 1000 damage per match. For paint, I recommend all black so everyone knows you're for serious. A white Cartoon Skull over the head/cockpit fools enemies into thinking you're an Atlas, gaining you a significant tactical advantage.
