Scout weapon idea

Now im sure things can be tweaked this way and that but here goes

Baseball helmet (Replaces the pistol)
What it could possibly do to increase scout playability on maps like goldrush or dustbowl is when
you crouch while wearing the baseball helmet your damage recieved would be reduced by 50% ( Or whatever percentage suitable)
(when standing or moving the baseball hat does nothing) (maybe something suggestions?)
Replaces pistol or quite possibly scattergun (not likely)

Now that was the sort of idea I had in my head is that a scouts function is to for the most part to be fast moving for the purpose of capturing intel and reaching capture points first.  The drawback of speed however is low hitpoints and being vulnerable. on that point

With the Baseball Helmet (I hope thats the right word?) is that using your quick speed to reach areas like the cart or capture points is when you reach the area you crouch and while crouching the helmets effect comes into the play

Ususally on maps involving capture points scouts rush it but when confronted usually run away, with the helmet causing damage reduction the scout could try and squeeze every last extra second in capturing a point or pushing the cart just a little bit more to helpout the team.  Since they have double effect for capturing it would be a valuable asset

Now if it replaces the scatter gun the scout would have to use the pistol, and visa versa which I wouldnt be compeltely sure how it would effect gameplay, but since scouts usually use pistols at a distance and if they are capturing a point im sure they would still be little problems.

or if it replaces the pistol then the scout would be crouched camping the area prepared for up close encounters?

Or maybe have the baseball cap as the melee weapon itself which would be held in the hand and used to attack people with but when crouching and clicking fire you would put it on and autoamtically pull out the pistol or scatter gun, but im sure if you ran out of ammo there would be issues.

But im rambling on now would people like to critique my suggestion?
