Since you can trasnform into a werewolf, why not have the option of being transform into a dragon through intensive training and test? Since you are dragonborn after all.

My solution...... To do this you must kill a partcular elder dragon (Obviously he will be a tough SOB) and collect at least 50 dragon bones and scales including 10 dragon hearts.

After you do transform, and according to your level, you would have the power and strength as an elder dragon.

Pro: Flying abilties, Dragon apperence, blowing fire/ice/etc.
Con: The villegers and big cities citizens, guards included will attack you like any other dragons that goes near them.

You will be given a warning indicator that you are about to change back into a human.... if you ignore it and transform while flying... you die.

To get this transformation you need to speak to paarthurnax.

Does anyone else think this would be a great addition?

It is a cool concept. Maybe someone will mod it I doubt it would ever make DLC.

After I submitted the post more ideas came to my head.

As for the strength and power their should be a whole new perk section to make your dragon power stronger.

From Novice to Mastery. You learn how to blow fire/ice... depending on what you choose (Fire dragon to ice dragon).
