Definitely. Shinigami like Hitsugaya, Yamamoto and my own Seia already do so. They're Reiatsu is an elemental representative of whatever element (Ice, Fire, Lightning in the above cases) and with enough training one can learn to manipulate their Reiatsu to achieve effects (Yamamoto likes to burn things as you might have guessed).
