Project NEMESIS

Hi all,
I'm a newbie who got turned on to Wild Talents by one of my mates at MK-RPG.
I'm now thinking of running an ongoing game using Wild talents in the Warren Ellis parts of the Wildstorm Universe. The basic plan is that the players are basic superheroes who will start off in Stormwatch, get 'promoted' to Stormwatch Black and then become the Authority.
I have the Authority RPG as a reference. Do people think Wild Talents will be suitable for this scenario? Know of any sites that have good DC/Marvel heroes/Wild Talents conversions? I plan over the next few weeks to start converting Wildstorm characters into Wild Talents to get used to how the system works.
Apologies if any of these questions have been answered elsewhere. I haven't had a chance to read everything yet.

I don't know of any existing Authority conversions, but I would love to see them if you write any up.
