Guzzle is likely also going to be a modified Warpath. Hound makes the most sense for Ironfist. Pyro is Inferno, of course. Rotorstorm will likely be the Tomahawk mold. Scoop from Cybertron landmine? Top Spin and Twin Twist are the most problematic ones. They'd have to be new molds, none of the recent molds really suit them.
