I was thinking along those lines. Instead of transforming into a dragon, you transform into a sort of Hybrid, with increased magic health and shout damage/recharge time, and an awesome scaly look to you. The fire/frost beath upgrades would be a continuous stream of each, like a dragons, until your special shout bar runs out. Also, abilities like Alduins meteor call and Fog.
