Leather-face Ultra rare add-on: Friendly Face

If leatherface putting a mask on doesn't work, then why not put one on his chainsaw too? That is what the survivors are running from after all!

Leatherface covers the chainsaw base with a survivor face and TREMENDOUSLY reduces the noise made by the chainsaw and reducing his terror radius to 0 while the chainsaw is charged.

I was thinking of add ons for killers which do not have ultra rares, and having played a lot of leatherface myself, thought about what would be good on him, but also fun for users while being fair on the survivor side.

Let me know what you guys think or if something like this would even be possible!
