add more 1800-1900 weapons

[kaiohsb]

I have an idea for a mod. There are many identical weapons in Red Dead Redemption 2 that only differ in appearance (such as engravings and carvings, like Emmet's and Flaco's revolvers, which are just Cattleman revolvers with some different engravings and carvings). Additionally, there's a gap in the weapon categories; for example, the absurd difference between the Springfield Rifle and the Bolt Action Rifle, with no middle ground between the two. This happens across various classes.

I had the idea to add the following rifles:

Vetterli-Vitali (a slightly faster alternative to the Springfield Rifle)
Martini-Henry (slower than the Rolling Block)
Mauser 98 (a faster alternative to the Bolt Action)
Mannlicher (an alternative to the Bolt Action)
Berthier (an alternative to the Carcano)
Meunier (a faster Carcano option)
Mosin-Nagant (an alternative to the Bolt Action)
Lee-Enfield (faster with lower damage)
Arisaka (an alternative to the Lee-Enfield)
Gewehr 98 (an alternative to the Mauser)
Winchester 1895 Russian Model (a lever-action rifle with better range)
For pistols and revolvers:

Mars Automatic (high damage, low rate of fire, and high recoil)
Bergmann N4 (an alternative to the Mauser 96)
Revolver MK3 (an alternative to the Double Action Revolver)
Remington 1858 (a middle ground alternative to the Navy Revolver)
I’d love for someone to make a mod like this or at least help me with it. I’m trying to learn but I’m struggling with file format conversions.
