I think Ice would be possible, as far as I can tell the term "Pyromancy," in 40k is actually the ability to change Warp energy into something else, such as ice or fire, and they use fire more often because it seems to be the most effective element for combat, although instead of just ice I would say the psyker could drain heat and control extreme cool.
