Time SWEP

So, you’ve got your Time Control and Time Grenade and such. But what about a weapon which you fire at something to slow it down? For example: You’re being attacked by a combine so you aim and fire the Time Swep at him to slow his movements down and dodge all of his attacks. You could also use it on props, so they move slower than the rest of the world.
Is this mildly possible? If so, could somebody have a crack at it?
