Is this possible as far as Mafia 3 modding goes?

[gnampf]

So I'm looking at the inside look thing for "Faster Baby" and I'm thinking "holy shit" because I remember up until a few years ago I was wanting to make a video game sorta like this, some pot dealers going up against the local government in a small rural town. I had a bunch of models made for it but then I let it go to focus on other things. Now it's years later and it turns out that my initial idea is now turning into a DLC for Mafia 3.

So for the sake of nostalgia and running blindly through memory lane, I'm wondering if there's any tools out there to edit the soundtracks (aren't they just one continuous loop like in the older GTA games?), change the textures, and replace car models so I can make the atmosphere for "Faster Baby" a bit more like what I was wanting to make. I know stuff like that is possible in GTA, but I don't know if it's possible yet in Mafia 3, or if there really isn't a modding scene for Mafia 3. All I've really seen are scripthooks and trainers, and that really isn't what I'm looking for, so I don't know if any of you guys would know about the modding tools and capabilities for this game or not.
