I've seen a lot of squads like this with Squad Leader + fodder. The problem becomes that your opponent knows this, and so can easily pick off the fodder first, making Swarm Leader useless, or take on the leader first, and the rest of the list doesn't have much teeth. It's really hard to design a list that can effectively use Swarm Leader. The most effective lists I've seen have been Rebel lists with Jess Pava and A-wings. Not saying it isn't possible to put together a good Swarm Leader list on Imperial side, but I just haven't seen many effective ones out there. Vessery as a Swarm Leader comes to mind.

I think you are on the right track with the free evades from the v1 title. But maybe try it with two Delta Squadron x7 Defenders. You can throw Mk II engines on both to make clearing stress much easier, and then throw some a Homing Missiles on Vader. If he gets in range and the defenders aren't, he still gets a powerful attack he can use. Plus still makes him dangerous even if they go after the defenders first. And at PS1, you have a good chance of making sure you get the evade token with the new errata to the x7, and can set up blocks with them as well.

That's just my opinion though. Fly what you like to fly is the big thing. If you put that list on the table and like it, then go for it.
