SFX Swap

I’ve seen a few mod requests and so I thought I’d ask,
Is there any way I could replace the gun sfx in Halo 4 with the sounds from Halo Reach? The ones in 4 are alright, but the sfx in Reach just have such a nice feel to them if that makes sense. I was wondering if there’s like a mod or something for this, or some way to replace the files manually. If there isn’t a way then it’s totally fine, I just was curious if this was possible.
