Yeah I just used the new Cold Ones popped on the Ulthwe Storm Guardian heads, and a Dire Avenger head for the Exarch, and then added laser lances.
I finished making a regular Jetbike Squad as well using the new Cold Ones too (which I'll post soon), and did a neat conversion for the Shuriken Cannon model, using the Autarch reaper missile launcher, and an old shuriken venom cannon. I think the paint job on the forthcoming models looks a lot better because I primed them white. I'll add new photos this week I swear.
