Alpha Legion in Killteam?

So, I made a cross continental move recently, and unfortunately I had to leave my entire 40k collection behind. I miss the hobby, but don't have the drive to go about replacing my entire collection. I was looking into Killteam as a way to get back into the hobby without having to go through the trouble of building a whole new army, and I've decided to make an Alpha Legion killteam for my first project. I've got a few questions as far as how to proceed.

One, seeing as how AL doesn't have a dedicated Killteam (mind blowing to me, they're literally the legion that would field something like that), what team do you feel best represents the AL out of the choices available? I was thinking either Legionnaires or a proxied Nemesis Claw. Thoughts?

Second, show me your kill teams! I'm looking for some inspiration :D My favorite part of the hobby is converting models, so I'd love to see what some of you have come up with!

Third, who has the best recipe for Alpha Legion metallic green?

Thanks all!
