That does bring up a interesting point. Unlike micarta and G-10 the only CF knife scales that I've ever seen have been flat. The Kiwi handle is rounded. That would pretty well rule out anything with a texture since it's the outer surface which has to be shaped down to fit the knife, then re-polished. While micarta and G-10 look great when contoured and polished, not sure if, or how well, that would work with CF.
If you're still considering the idea, I'd suggest checking with Bill as to how thick (minimum) CF you would need, then seeing what Dragonplate
has to offer.
