Singularity Time manipulation device

If anyone got Singularity you would know what Im talking about. If not go here: http://www.gamespot.com/pc/action/singularity/index.html

So Im wondering If someone could make this a swep. Im thinking you would go about doing this by making a model of the hevsuit hand/arm with the tmd on it, then making a swep that uses the model that acts like the gravity gun. Then figure out how to do the age / de-age thing. Any flaws in my thinking?
