Multiple requests including animations, skins, and drop item

So to be clear I'm a noob at modding so forgive ignorance on the lack of technical knowledge but would it be possible to add a pick animation for picking up items like in RE5? Having Leon pick up health or money from fallen enemies would add more of that classic resident evil trilogy vibe. Ashley has an animation for it in one moment of the game where she picks up a key so could that not be applied to Leon in some way? Another thing from RE5 that would be cool to implement would be visible weapons on Leon like when he has a shotgun or rifle in his inventory it would be attached to his back during game play when unequipped along with other weapons similarly to when he has grenades strapped to his belt. I remember seeing a mod of this once on YouTube years ago but haven't been able to find it since anywhere online, so it does exist somewhere out there. What about being able to use killed enemy weapons like rocket launchers of dead soldiers on the island section instead of them disappearing. As to making the game even more immersive and challenging how about eliminating ammo drops from enemies and having them only drop treasures or money instead as that would make much more sense lore wise and instead having the merchant be able to sell ammo, which there is a functioning mod for already and I have it downloaded. Idk how practical these requests are but there just some ideas. Let me know what you guys think.
