I've been flying something similar to the Bren list, but I'm using two Tie Advanced with title and Accuracy Correctors, and have thrown a Hull Upgrade on Omega Ace.
I've only really flown it once, it was fun and I can see the potential power. A fun thing with this kind of swarm is that you don't really need to fly in formation, as Swarm Leader triggers as long as ships have the same target in arc/range. I like to take evade as an action with Omega Ace and then load up with Focus and Target lock from System/Fleet Officer, triggering Cool Hand for an Evade. That gives both ships decent defense.
Reading this thread has got me wanting to get Kylo in there though, would be fun.
