If GW gave you the ability to choose which space marine chapter to get a new range of unique minatures (or even their own supplementary codex on top of it like the Black Templars did), which one would you choose?
Remember, this can be any chapter that has little or no presence in the 40k game right now (HH doesn't count). This could be a founding chapter like the Salamanders or Iron Hands, a successor chapter like the Crimson Fists or Carchadons, or something obscure like the White Consuls or Steel Confessors.
For me, I'd like to see Iron Hands, Salamanders, or the Carchadons myself, since they have loads of potential for unique minatures and rules. Iron Hands got their cyborg space marines and heavy tech support, Salamanders got their "Burn the impure" angle, and Carchadons are just plain bad-ass like their alpha, Tyberos the Red Wake.
On an additional note, if this included Chaos chapters, who'd you choose? For me, I'd love to see the modern presence of the Night Lords (became one of my favorite traitor chapters after reading their triology books), and the Iron Warriors (that one could happen since Perturabo is hinted to be coming to the 40k game at some point).
But anyway, I'd love to hear your thoughts.
