I doubt it :(
Those live walpapers are not only coded in Java, but they reference Android native code directly which is not possible as far as I know. The only ways or creating an android app using C2 is to use PhoneGap, CocoonJS or Clay.IO (have i missed any?), and I know for a fact that Clay.IO does not export live wallpapers.
Then again, I bet there is someone in the C2 community that would make an exporter for a Live Wallpaper, but for that to happen, we have to implement exporting HTML5/CSS3/JS directly to Android first from the C2 environment, without a middleman. When this is done, then it's almost certain that Andorid Live Wallpapers will follow almost immediately.
But for now, I don't think it's possible, unless someone has found a way how. Sorry about that :( it would be an awesome feature as well...
