You can use a prop_dynamic to scale props, but you can't preview that scale in Hammer and the hitbox of the model will not scale with it.

CS:GO has static prop resizing, but CS:GO also has an entirely rewritten bsp system that TF2 does not have.

What prop is it that you want to scale up, anyway? Keep in mind that the textures were made with the normal size in mind. It's likely to look low-res and blurry if it's much bigger than that.
