Anyone else think this is a cool idea? If I ended up making them, I'd probably just play them as Cold one Riders, perhaps with Halberds if my opponent permitted, but how are they fluff wise? Also, I think they'd be fairly easy to convert with a cold one riders kit, a temple guard kit, and a little green stuff. I'd love to hear your opinions on them!
I think the temple guard plastics are some of the best in the lizardmen army, and that the cold one riders are one of the neatest units in the army. Combining the two sounds like victory, win and sucess combined to me.
